Check Digit Verification of cas no

The CAS Registry Mumber 21191-40-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,9 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21191-40:
(7*2)+(6*1)+(5*1)+(4*9)+(3*1)+(2*4)+(1*0)=72
72 % 10 = 2
So 21191-40-2 is a valid CAS Registry Number.
