Check Digit Verification of cas no

The CAS Registry Mumber 253447-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,4,4 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 253447-23:
(8*2)+(7*5)+(6*3)+(5*4)+(4*4)+(3*7)+(2*2)+(1*3)=133
133 % 10 = 3
So 253447-23-3 is a valid CAS Registry Number.
