Check Digit Verification of cas no

The CAS Registry Mumber 1246370-19-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,6,3,7 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1246370-19:
(9*1)+(8*2)+(7*4)+(6*6)+(5*3)+(4*7)+(3*0)+(2*1)+(1*9)=143
143 % 10 = 3
So 1246370-19-3 is a valid CAS Registry Number.
