Check Digit Verification of cas no

The CAS Registry Mumber 7699-82-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,9 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7699-82:
(6*7)+(5*6)+(4*9)+(3*9)+(2*8)+(1*2)=153
153 % 10 = 3
So 7699-82-3 is a valid CAS Registry Number.
