Check Digit Verification of cas no

The CAS Registry Mumber 19809-79-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,0 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 19809-79:
(7*1)+(6*9)+(5*8)+(4*0)+(3*9)+(2*7)+(1*9)=151
151 % 10 = 1
So 19809-79-1 is a valid CAS Registry Number.
