Check Digit Verification of cas no

The CAS Registry Mumber 2793-17-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,9 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2793-17:
(6*2)+(5*7)+(4*9)+(3*3)+(2*1)+(1*7)=101
101 % 10 = 1
So 2793-17-1 is a valid CAS Registry Number.
