Check Digit Verification of cas no

The CAS Registry Mumber 264-14-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,6 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 264-14:
(5*2)+(4*6)+(3*4)+(2*1)+(1*4)=52
52 % 10 = 2
So 264-14-2 is a valid CAS Registry Number.
