112424-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112424-21-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,4,2 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 112424-21:
(8*1)+(7*1)+(6*2)+(5*4)+(4*2)+(3*4)+(2*2)+(1*1)=72
72 % 10 = 2
So 112424-21-2 is a valid CAS Registry Number.
