Check Digit Verification of cas no

The CAS Registry Mumber 872425-33-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,2,4,2 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 872425-33:
(8*8)+(7*7)+(6*2)+(5*4)+(4*2)+(3*5)+(2*3)+(1*3)=177
177 % 10 = 7
So 872425-33-7 is a valid CAS Registry Number.

Al-Mousawi, Saleh Mohammed,El-Apasery, Morsy Ahmed

, p. 8837 - 8844 (2013)

A series of azo disperse dyes based on aminothienochromene were synthesized. The fastness properties of the dyed samples were measured. Most of the dyed fabrics tested displayed excellent washing and perspiration fastness and moderate light fastness.
