104275-38-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104275-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,2,7 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 104275-38:
(8*1)+(7*0)+(6*4)+(5*2)+(4*7)+(3*5)+(2*3)+(1*8)=99
99 % 10 = 9
So 104275-38-9 is a valid CAS Registry Number.
