104475-97-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104475-97-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,4,7 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 104475-97:
(8*1)+(7*0)+(6*4)+(5*4)+(4*7)+(3*5)+(2*9)+(1*7)=120
120 % 10 = 0
So 104475-97-0 is a valid CAS Registry Number.
