Check Digit Verification of cas no

The CAS Registry Mumber 14949-21-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,9,4 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 14949-21:
(7*1)+(6*4)+(5*9)+(4*4)+(3*9)+(2*2)+(1*1)=124
124 % 10 = 4
So 14949-21-4 is a valid CAS Registry Number.
