Check Digit Verification of cas no

The CAS Registry Mumber 1002921-57-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,2,9,2 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1002921-57:
(9*1)+(8*0)+(7*0)+(6*2)+(5*9)+(4*2)+(3*1)+(2*5)+(1*7)=94
94 % 10 = 4
So 1002921-57-4 is a valid CAS Registry Number.
