39920-04-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 39920-04-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,9,2 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 39920-04:
(7*3)+(6*9)+(5*9)+(4*2)+(3*0)+(2*0)+(1*4)=132
132 % 10 = 2
So 39920-04-2 is a valid CAS Registry Number.
