Check Digit Verification of cas no

The CAS Registry Mumber 132415-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,4,1 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 132415-12:
(8*1)+(7*3)+(6*2)+(5*4)+(4*1)+(3*5)+(2*1)+(1*2)=84
84 % 10 = 4
So 132415-12-4 is a valid CAS Registry Number.

Polyfunctional α-diazo-β-keto esters and their use in light-sensitive compositions

-

, (2008/06/13)

Polyfunctional α-diazo-β-keto esters of the general formula I are described STR1 in which R1 denotes an aliphatic, cycloaliphatic or araliphatic or aromatic radical having 4 to 20 carbon atoms, in which individual CH2 groups can be replaced by oxygen or sulfur atoms or by N-- or NH groups and/or contain keto groups, X denotes an aliphatic, cycloaliphatic, carbocyclic, heterocyclic or araliphatic radical having 2 to 22 carbon atoms, in which individual CH2 groups can be replaced by oxygen or sulfur atoms or by the groups STR2 in which R2 and R3 independently of one another represent hydrogen or an aliphatic, carbocyclic or araliphatic radical, m denotes an integer from 2 to 10 and n denotes an integer from 0 to 2, wherein m-n is ≥2. The compounds mentioned are used as photoactive components in radiation-sensitive mixtures.
