112331-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112331-21-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,3,3 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 112331-21:
(8*1)+(7*1)+(6*2)+(5*3)+(4*3)+(3*1)+(2*2)+(1*1)=62
62 % 10 = 2
So 112331-21-2 is a valid CAS Registry Number.
