104480-74-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104480-74-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,4,8 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 104480-74:
(8*1)+(7*0)+(6*4)+(5*4)+(4*8)+(3*0)+(2*7)+(1*4)=102
102 % 10 = 2
So 104480-74-2 is a valid CAS Registry Number.
