104654-49-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104654-49-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,6,5 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 104654-49:
(8*1)+(7*0)+(6*4)+(5*6)+(4*5)+(3*4)+(2*4)+(1*9)=111
111 % 10 = 1
So 104654-49-1 is a valid CAS Registry Number.
