299914-24-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 299914-24-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,9,9,1 and 4 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 299914-24:
(8*2)+(7*9)+(6*9)+(5*9)+(4*1)+(3*4)+(2*2)+(1*4)=202
202 % 10 = 2
So 299914-24-2 is a valid CAS Registry Number.
