Check Digit Verification of cas no

The CAS Registry Mumber 1257423-40-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,4,2 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1257423-40:
(9*1)+(8*2)+(7*5)+(6*7)+(5*4)+(4*2)+(3*3)+(2*4)+(1*0)=147
147 % 10 = 7
