Check Digit Verification of cas no

The CAS Registry Mumber 157557-07-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,5,5 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 157557-07:
(8*1)+(7*5)+(6*7)+(5*5)+(4*5)+(3*7)+(2*0)+(1*7)=158
158 % 10 = 8
So 157557-07-8 is a valid CAS Registry Number.
