Check Digit Verification of cas no

The CAS Registry Mumber 64890-21-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,8,9 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 64890-21:
(7*6)+(6*4)+(5*8)+(4*9)+(3*0)+(2*2)+(1*1)=147
147 % 10 = 7
So 64890-21-7 is a valid CAS Registry Number.
