Check Digit Verification of cas no

The CAS Registry Mumber 1660146-12-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,6,0,1,4 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1660146-12:
(9*1)+(8*6)+(7*6)+(6*0)+(5*1)+(4*4)+(3*6)+(2*1)+(1*2)=142
142 % 10 = 2
So 1660146-12-2 is a valid CAS Registry Number.
