Check Digit Verification of cas no

The CAS Registry Mumber 793-42-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,9 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 793-42:
(5*7)+(4*9)+(3*3)+(2*4)+(1*2)=90
90 % 10 = 0
So 793-42-0 is a valid CAS Registry Number.
