1131428-75-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1131428-75-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,1,4,2 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1131428-75:
(9*1)+(8*1)+(7*3)+(6*1)+(5*4)+(4*2)+(3*8)+(2*7)+(1*5)=115
115 % 10 = 5
So 1131428-75-5 is a valid CAS Registry Number.
