137761-03-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 137761-03-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,7,6 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 137761-03:
(8*1)+(7*3)+(6*7)+(5*7)+(4*6)+(3*1)+(2*0)+(1*3)=136
136 % 10 = 6
So 137761-03-6 is a valid CAS Registry Number.

Stereochemically matched sulfinylacetates for double diastereoselection in the spac reaction

Burgess, Kevin,Henderson, Ian

, p. 6601 - 6616 (1991)

4-Chlorophenylsulfinylacetates of defined stereochemistry at sulfur were prepared from monochiral alcohols: compound 2 from (+)-menthol; 3 and 4 from (-)-8-phenylmenthol; 5 and 6 from (+)-trans-2-phenylcyclohexanol; and, 7 and 9 from (-)-10-dicyclohexylsulfamoyl-D-isoborneol. Reagents for which the sulfoxide asymmetry is matched with the inducing effect of the auxiliary give good diastereoselection in SPAC reactions affording γ-hydroxy-α,β-unsaturatod alcohols of high optical purity. Asymmetry at the sulfoxide has a greater effect than the auxiliaries on the stereochemical outcome of these reactions.
