39974-52-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 39974-52-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,9,7 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 39974-52:
(7*3)+(6*9)+(5*9)+(4*7)+(3*4)+(2*5)+(1*2)=172
172 % 10 = 2
So 39974-52-2 is a valid CAS Registry Number.
