Check Digit Verification of cas no

The CAS Registry Mumber 201990-83-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,9,9 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 201990-83:
(8*2)+(7*0)+(6*1)+(5*9)+(4*9)+(3*0)+(2*8)+(1*3)=122
122 % 10 = 2
So 201990-83-2 is a valid CAS Registry Number.
