Check Digit Verification of cas no

The CAS Registry Mumber 1189342-34-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,3,4 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1189342-34:
(9*1)+(8*1)+(7*8)+(6*9)+(5*3)+(4*4)+(3*2)+(2*3)+(1*4)=174
174 % 10 = 4
So 1189342-34-4 is a valid CAS Registry Number.

Click à la carte: robust semi-orthogonal alkyne protecting groups for multiple successive azide/alkyne cycloadditions

Valverde, Ibai E.,Delmas, Agnès F.,Aucagne, Vincent

experimental part, p. 7597 - 7602 (2009/12/04)

We herein describe an in-depth screening and systematic comparison of five classical silyl alkyne protective groups, to evaluate their potential in the context of multiple successive copper (I)-catalyzed alkyne-azide cycloadditions (CuAAC). We confirm the
