104272-99-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104272-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,2,7 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 104272-99:
(8*1)+(7*0)+(6*4)+(5*2)+(4*7)+(3*2)+(2*9)+(1*9)=103
103 % 10 = 3
So 104272-99-3 is a valid CAS Registry Number.
