Check Digit Verification of cas no

The CAS Registry Mumber 649719-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,9,7,1 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 649719-57:
(8*6)+(7*4)+(6*9)+(5*7)+(4*1)+(3*9)+(2*5)+(1*7)=213
213 % 10 = 3
So 649719-57-3 is a valid CAS Registry Number.
