104273-06-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104273-06-5 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 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 104273-06:
(8*1)+(7*0)+(6*4)+(5*2)+(4*7)+(3*3)+(2*0)+(1*6)=85
85 % 10 = 5
So 104273-06-5 is a valid CAS Registry Number.
