Check Digit Verification of cas no

The CAS Registry Mumber 1187767-40-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,7,6 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1187767-40:
(9*1)+(8*1)+(7*8)+(6*7)+(5*7)+(4*6)+(3*7)+(2*4)+(1*0)=203
203 % 10 = 3
So 1187767-40-3 is a valid CAS Registry Number.
