Check Digit Verification of cas no

The CAS Registry Mumber 229976-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,9,9,7 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 229976-40:
(8*2)+(7*2)+(6*9)+(5*9)+(4*7)+(3*6)+(2*4)+(1*0)=183
183 % 10 = 3
So 229976-40-3 is a valid CAS Registry Number.
