Check Digit Verification of cas no

The CAS Registry Mumber 64202-49-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,2,0 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 64202-49:
(7*6)+(6*4)+(5*2)+(4*0)+(3*2)+(2*4)+(1*9)=99
99 % 10 = 9
So 64202-49-9 is a valid CAS Registry Number.
