104875-25-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104875-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,8,7 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 104875-25:
(8*1)+(7*0)+(6*4)+(5*8)+(4*7)+(3*5)+(2*2)+(1*5)=124
124 % 10 = 4
So 104875-25-4 is a valid CAS Registry Number.
