104427-20-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104427-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,4,2 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 104427-20:
(8*1)+(7*0)+(6*4)+(5*4)+(4*2)+(3*7)+(2*2)+(1*0)=85
85 % 10 = 5
So 104427-20-5 is a valid CAS Registry Number.
