104705-94-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104705-94-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,7,0 and 5 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 104705-94:
(8*1)+(7*0)+(6*4)+(5*7)+(4*0)+(3*5)+(2*9)+(1*4)=104
104 % 10 = 4
So 104705-94-4 is a valid CAS Registry Number.
