Check Digit Verification of cas no

The CAS Registry Mumber 345625-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,5,6,2 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 345625-70:
(8*3)+(7*4)+(6*5)+(5*6)+(4*2)+(3*5)+(2*7)+(1*0)=149
149 % 10 = 9
So 345625-70-9 is a valid CAS Registry Number.
