Check Digit Verification of cas no

The CAS Registry Mumber 1620145-05-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,1,4 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1620145-05:
(9*1)+(8*6)+(7*2)+(6*0)+(5*1)+(4*4)+(3*5)+(2*0)+(1*5)=112
112 % 10 = 2
So 1620145-05-2 is a valid CAS Registry Number.
