Check Digit Verification of cas no

The CAS Registry Mumber 3763-39-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,6 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3763-39:
(6*3)+(5*7)+(4*6)+(3*3)+(2*3)+(1*9)=101
101 % 10 = 1
So 3763-39-1 is a valid CAS Registry Number.
