Check Digit Verification of cas no

The CAS Registry Mumber 4641-83-2 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 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4641-83:
(6*4)+(5*6)+(4*4)+(3*1)+(2*8)+(1*3)=92
92 % 10 = 2
So 4641-83-2 is a valid CAS Registry Number.
