Check Digit Verification of cas no

The CAS Registry Mumber 4643-82-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,4 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4643-82:
(6*4)+(5*6)+(4*4)+(3*3)+(2*8)+(1*2)=97
97 % 10 = 7
So 4643-82-7 is a valid CAS Registry Number.
