Check Digit Verification of cas no

The CAS Registry Mumber 421-22-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 421-22:
(5*4)+(4*2)+(3*1)+(2*2)+(1*2)=37
37 % 10 = 7
So 421-22-7 is a valid CAS Registry Number.
