Check Digit Verification of cas no

The CAS Registry Mumber 1620159-91-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,1,5 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1620159-91:
(9*1)+(8*6)+(7*2)+(6*0)+(5*1)+(4*5)+(3*9)+(2*9)+(1*1)=142
142 % 10 = 2
So 1620159-91-2 is a valid CAS Registry Number.
