Check Digit Verification of cas no

The CAS Registry Mumber 64462-68-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,4,6 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 64462-68:
(7*6)+(6*4)+(5*4)+(4*6)+(3*2)+(2*6)+(1*8)=136
136 % 10 = 6
So 64462-68-6 is a valid CAS Registry Number.
