Check Digit Verification of cas no

The CAS Registry Mumber 1042139-01-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,2,1,3 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1042139-01:
(9*1)+(8*0)+(7*4)+(6*2)+(5*1)+(4*3)+(3*9)+(2*0)+(1*1)=94
94 % 10 = 4
So 1042139-01-4 is a valid CAS Registry Number.
