Check Digit Verification of cas no

The CAS Registry Mumber 612090-74-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,2,0,9 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 612090-74:
(8*6)+(7*1)+(6*2)+(5*0)+(4*9)+(3*0)+(2*7)+(1*4)=121
121 % 10 = 1
So 612090-74-1 is a valid CAS Registry Number.
