Check Digit Verification of cas no

The CAS Registry Mumber 4546-21-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,4 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4546-21:
(6*4)+(5*5)+(4*4)+(3*6)+(2*2)+(1*1)=88
88 % 10 = 8
So 4546-21-8 is a valid CAS Registry Number.
