114431-76-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 114431-76-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,4,3 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 114431-76:
(8*1)+(7*1)+(6*4)+(5*4)+(4*3)+(3*1)+(2*7)+(1*6)=94
94 % 10 = 4
So 114431-76-4 is a valid CAS Registry Number.
