Check Digit Verification of cas no

The CAS Registry Mumber 1344672-00-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,4,6,7 and 2 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1344672-00:
(9*1)+(8*3)+(7*4)+(6*4)+(5*6)+(4*7)+(3*2)+(2*0)+(1*0)=149
149 % 10 = 9
So 1344672-00-9 is a valid CAS Registry Number.
