Check Digit Verification of cas no
The CAS Registry Mumber 1334722-49-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,7,2 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1334722-49:
(9*1)+(8*3)+(7*3)+(6*4)+(5*7)+(4*2)+(3*2)+(2*4)+(1*9)=144
144 % 10 = 4
So 1334722-49-4 is a valid CAS Registry Number.
