Check Digit Verification of cas no

The CAS Registry Mumber 1239700-90-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,7,0 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1239700-90:
(9*1)+(8*2)+(7*3)+(6*9)+(5*7)+(4*0)+(3*0)+(2*9)+(1*0)=153
153 % 10 = 3
