1334109-69-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1334109-69-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,1,0 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1334109-69:
(9*1)+(8*3)+(7*3)+(6*4)+(5*1)+(4*0)+(3*9)+(2*6)+(1*9)=131
131 % 10 = 1
So 1334109-69-1 is a valid CAS Registry Number.
