Check Digit Verification of cas no

The CAS Registry Mumber 291506-55-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,1,5,0 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 291506-55:
(8*2)+(7*9)+(6*1)+(5*5)+(4*0)+(3*6)+(2*5)+(1*5)=143
143 % 10 = 3
So 291506-55-3 is a valid CAS Registry Number.
