Check Digit Verification of cas no

The CAS Registry Mumber 1021949-25-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,9,4 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1021949-25:
(9*1)+(8*0)+(7*2)+(6*1)+(5*9)+(4*4)+(3*9)+(2*2)+(1*5)=126
126 % 10 = 6
So 1021949-25-6 is a valid CAS Registry Number.
