Check Digit Verification of cas no

The CAS Registry Mumber 3716-28-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,1 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3716-28:
(6*3)+(5*7)+(4*1)+(3*6)+(2*2)+(1*8)=87
87 % 10 = 7
So 3716-28-7 is a valid CAS Registry Number.
