Check Digit Verification of cas no

The CAS Registry Mumber 157577-99-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,5,7 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 157577-99:
(8*1)+(7*5)+(6*7)+(5*5)+(4*7)+(3*7)+(2*9)+(1*9)=186
186 % 10 = 6
So 157577-99-6 is a valid CAS Registry Number.
