Check Digit Verification of cas no

The CAS Registry Mumber 121374-52-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,3,7 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 121374-52:
(8*1)+(7*2)+(6*1)+(5*3)+(4*7)+(3*4)+(2*5)+(1*2)=95
95 % 10 = 5
So 121374-52-5 is a valid CAS Registry Number.
