431985-11-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 431985-11-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,1,9,8 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 431985-11:
(8*4)+(7*3)+(6*1)+(5*9)+(4*8)+(3*5)+(2*1)+(1*1)=154
154 % 10 = 4
So 431985-11-4 is a valid CAS Registry Number.
