Check Digit Verification of cas no

The CAS Registry Mumber 621-89-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 621-89:
(5*6)+(4*2)+(3*1)+(2*8)+(1*9)=66
66 % 10 = 6
So 621-89-6 is a valid CAS Registry Number.
