39140-40-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 39140-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,1,4 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 39140-40:
(7*3)+(6*9)+(5*1)+(4*4)+(3*0)+(2*4)+(1*0)=104
104 % 10 = 4
So 39140-40-4 is a valid CAS Registry Number.
