104994-71-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104994-71-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,9,9 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 104994-71:
(8*1)+(7*0)+(6*4)+(5*9)+(4*9)+(3*4)+(2*7)+(1*1)=140
140 % 10 = 0
So 104994-71-0 is a valid CAS Registry Number.
