Check Digit Verification of cas no

The CAS Registry Mumber 7696-71-1 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 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7696-71:
(6*7)+(5*6)+(4*9)+(3*6)+(2*7)+(1*1)=141
141 % 10 = 1
So 7696-71-1 is a valid CAS Registry Number.
