Check Digit Verification of cas no

The CAS Registry Mumber 3196-34-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,9 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3196-34:
(6*3)+(5*1)+(4*9)+(3*6)+(2*3)+(1*4)=87
87 % 10 = 7
So 3196-34-7 is a valid CAS Registry Number.
