31952-24-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31952-24-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,9,5 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 31952-24:
(7*3)+(6*1)+(5*9)+(4*5)+(3*2)+(2*2)+(1*4)=106
106 % 10 = 6
So 31952-24-6 is a valid CAS Registry Number.
