Check Digit Verification of cas no

The CAS Registry Mumber 90771-85-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,7,7 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90771-85:
(7*9)+(6*0)+(5*7)+(4*7)+(3*1)+(2*8)+(1*5)=150
150 % 10 = 0
So 90771-85-0 is a valid CAS Registry Number.
