Check Digit Verification of cas no

The CAS Registry Mumber 769968-36-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,6,9,9,6 and 8 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 769968-36:
(8*7)+(7*6)+(6*9)+(5*9)+(4*6)+(3*8)+(2*3)+(1*6)=257
257 % 10 = 7
So 769968-36-7 is a valid CAS Registry Number.
