Check Digit Verification of cas no

The CAS Registry Mumber 557772-62-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,7,7,7 and 2 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 557772-62:
(8*5)+(7*5)+(6*7)+(5*7)+(4*7)+(3*2)+(2*6)+(1*2)=200
200 % 10 = 0
So 557772-62-0 is a valid CAS Registry Number.
