Check Digit Verification of cas no

The CAS Registry Mumber 91877-30-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,7 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 91877-30:
(7*9)+(6*1)+(5*8)+(4*7)+(3*7)+(2*3)+(1*0)=164
164 % 10 = 4
So 91877-30-4 is a valid CAS Registry Number.
