Check Digit Verification of cas no

The CAS Registry Mumber 642-27-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 2 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 642-27:
(5*6)+(4*4)+(3*2)+(2*2)+(1*7)=63
63 % 10 = 3
So 642-27-3 is a valid CAS Registry Number.
