Check Digit Verification of cas no

The CAS Registry Mumber 139746-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,7,4 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139746-45:
(8*1)+(7*3)+(6*9)+(5*7)+(4*4)+(3*6)+(2*4)+(1*5)=165
165 % 10 = 5
So 139746-45-5 is a valid CAS Registry Number.
