Check Digit Verification of cas no

The CAS Registry Mumber 664973-64-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,4,9,7 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 664973-64:
(8*6)+(7*6)+(6*4)+(5*9)+(4*7)+(3*3)+(2*6)+(1*4)=212
212 % 10 = 2
So 664973-64-2 is a valid CAS Registry Number.
