Check Digit Verification of cas no

The CAS Registry Mumber 1227940-01-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,9,4 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1227940-01:
(9*1)+(8*2)+(7*2)+(6*7)+(5*9)+(4*4)+(3*0)+(2*0)+(1*1)=143
143 % 10 = 3
So 1227940-01-3 is a valid CAS Registry Number.
