Check Digit Verification of cas no

The CAS Registry Mumber 140868-95-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,6 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 140868-95:
(8*1)+(7*4)+(6*0)+(5*8)+(4*6)+(3*8)+(2*9)+(1*5)=147
147 % 10 = 7
So 140868-95-7 is a valid CAS Registry Number.
