Check Digit Verification of cas no

The CAS Registry Mumber 213249-77-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,2,4 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 213249-77:
(8*2)+(7*1)+(6*3)+(5*2)+(4*4)+(3*9)+(2*7)+(1*7)=115
115 % 10 = 5
So 213249-77-5 is a valid CAS Registry Number.
