Check Digit Verification of cas no

The CAS Registry Mumber 143722-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,7,2 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 143722-33:
(8*1)+(7*4)+(6*3)+(5*7)+(4*2)+(3*2)+(2*3)+(1*3)=112
112 % 10 = 2
So 143722-33-2 is a valid CAS Registry Number.
