1334288-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1334288-89-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,2,8 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1334288-89:
(9*1)+(8*3)+(7*3)+(6*4)+(5*2)+(4*8)+(3*8)+(2*8)+(1*9)=169
169 % 10 = 9
So 1334288-89-9 is a valid CAS Registry Number.
