Check Digit Verification of cas no

The CAS Registry Mumber 199996-77-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,9,9 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 199996-77:
(8*1)+(7*9)+(6*9)+(5*9)+(4*9)+(3*6)+(2*7)+(1*7)=245
245 % 10 = 5
So 199996-77-5 is a valid CAS Registry Number.
