Check Digit Verification of cas no
The CAS Registry Mumber 1334919-19-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,9,1 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1334919-19:
(9*1)+(8*3)+(7*3)+(6*4)+(5*9)+(4*1)+(3*9)+(2*1)+(1*9)=165
165 % 10 = 5
So 1334919-19-5 is a valid CAS Registry Number.
