104344-02-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104344-02-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,3,4 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 104344-02:
(8*1)+(7*0)+(6*4)+(5*3)+(4*4)+(3*4)+(2*0)+(1*2)=77
77 % 10 = 7
So 104344-02-7 is a valid CAS Registry Number.
