104337-59-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104337-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,3,3 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 104337-59:
(8*1)+(7*0)+(6*4)+(5*3)+(4*3)+(3*7)+(2*5)+(1*9)=99
99 % 10 = 9
So 104337-59-9 is a valid CAS Registry Number.
