Check Digit Verification of cas no
The CAS Registry Mumber 90719-32-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,7,1 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90719-32:
(7*9)+(6*0)+(5*7)+(4*1)+(3*9)+(2*3)+(1*2)=137
137 % 10 = 7
So 90719-32-7 is a valid CAS Registry Number.

Paragraph 0044; 0049-0050, (2021/11/10)
The preparation method comprises the following steps 1): dissolving aromatic amino acid in methanol, dissolving the aromatic amino acid in methanol, heating up to 50 - 60 °C heat preservation 1 - 2h, 2) reducing: adding a catalytic amount of lithium salt in ethanol water as a solvent. 3) Ring-closing: toluene is used as a solvent, a reduction product and diethyl carbonate are added to 100 °C, a sodium methoxide solution is added dropwise, and the product is obtained after completion of the dropwise addition and after-treatment and purification after completion of the normal pressure distillation to the temperature of 100 °C heat preservation. The lithium salt is introduced to participate in the reaction, sodium borohydride is selected as a solvent, sodium borohydride is completely dissolved, and the lithium salt can be free from the compound to improve the reaction activity, so that the use amount of sodium borohydride is reduced to 2 equivalent, and the production cost is remarkably reduced.
Synthesis of pyrroloindolines through formal [3 + 2]-cycloaddition of indoles with chiral N-2-acetamidoacrylyl oxazolidinones

Chiral N-2-acetamidoacrylyl oxazolidinones were produced and reacted with indoles under Lewis acid conditions to generate hexahydropyrrolo[2,3-b]indole products in a formal [3 + 2] cycloaddition process. Optimal conditions included the use of tin(IV) chloride in methylene chloride at 0 °C. Pyrroloindoline products were obtained from various indoles with shorter reaction times (12 hr) up to 91% yield with high, >20:1 exo selectivity. A mechanism involving reversible conjugate addition followed by an enamine lone-pair-iminium capture, tautomerization, and tin-enolate protonation accounts for the selectivity. The method enables selective applications to pyrroloindoline targets and further refinement with chiral catalysts.
