Check Digit Verification of cas no
The CAS Registry Mumber 139347-71-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,4 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139347-71:
(8*1)+(7*3)+(6*9)+(5*3)+(4*4)+(3*7)+(2*7)+(1*1)=150
150 % 10 = 0
So 139347-71-0 is a valid CAS Registry Number.

Azide Ring-Opening-Ring-Closure Reactions and Tele-substitutions in Vicinal Azidopyrazole-, Pyrrole- and Indolecarboxaldehydes

5-Chloro-1-methylpyrazole-4-carboxaldehydes 1 react with excess sodium azide in dimethyl sulfoxide to produce a mixture of 1-azidomethyl-4-cyanopyrazoles 2 and 4-cyano-5-hydroxy-1-methylpyrazoles 3.Application of this reaction to the corresponding 5-chloro-1-phenylpyrazole-4-carboxaldehydes 5 gave 4-cyano-5-hydroxy-1-phenyl-pyrazoles 7 as the sole products in high yields.Likewise, 2-aryl-5-chloro-1-methylpyrrole-3,4-dicarboxaldehydes 9 rearranged to 2-aryl-4-cyano-5-hydroxy-1-methylpyrrole-3-carboxaldehydes 10 in high yields.In the indole series, treatment of 1-aryl-2-chloroindole-3-carboxaldehydes 11 with NaN3 yielded a mixture of 1-aryl-3-cyano-2(3H)-indolones 13 and 1-aryl-5-azido-3-cyanoindoles 12, both products resulting from a ring-opening-ring-closure reaction with concomitant nucleophilic tele-substitution at the 5-position of the indole ring.
