Check Digit Verification of cas no

The CAS Registry Mumber 941671-69-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,1,6,7 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 941671-69:
(8*9)+(7*4)+(6*1)+(5*6)+(4*7)+(3*1)+(2*6)+(1*9)=188
188 % 10 = 8
So 941671-69-8 is a valid CAS Registry Number.
