Check Digit Verification of cas no

The CAS Registry Mumber 123834-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,8,3 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 123834-90:
(8*1)+(7*2)+(6*3)+(5*8)+(4*3)+(3*4)+(2*9)+(1*0)=122
122 % 10 = 2
So 123834-90-2 is a valid CAS Registry Number.
