Check Digit Verification of cas no

The CAS Registry Mumber 77633-06-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,3 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 77633-06:
(7*7)+(6*7)+(5*6)+(4*3)+(3*3)+(2*0)+(1*6)=148
148 % 10 = 8
So 77633-06-8 is a valid CAS Registry Number.
