Check Digit Verification of cas no

The CAS Registry Mumber 187791-45-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,7,9 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 187791-45:
(8*1)+(7*8)+(6*7)+(5*7)+(4*9)+(3*1)+(2*4)+(1*5)=193
193 % 10 = 3
So 187791-45-3 is a valid CAS Registry Number.
