Check Digit Verification of cas no

The CAS Registry Mumber 137156-35-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,1,5 and 6 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137156-35:
(8*1)+(7*3)+(6*7)+(5*1)+(4*5)+(3*6)+(2*3)+(1*5)=125
125 % 10 = 5
So 137156-35-5 is a valid CAS Registry Number.

Study of the reactivity of nitriles towards diazomethane: synthesis and structural study of N-methyl-v-triazoles

Danoun, Saida,Baziard-Mouysset, Genevieve,Stigliani, Jean-Luc,Commenges, Gerard,Carpy, Alain,Payard, Marc

, p. 943 - 951 (2007/10/02)

In this work, we examined the effect of diazomethane on 12 nitriles.Five gave rise to three isomeric N-methyl-v-triazoles, which were isolated.Their structural features were established and, in one case, corroborated by X-ray analysis.A generalization of the structural attribution by 13C NMR is proposed.A study of the electronic distribution was carried out for a total 17 nitriles and helped establish a predictive criterion of their reactivity towards diazomethane. diazomethane / nitrile / v-triazole / electronic density
