1174398-04-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1174398-04-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,4,3,9 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1174398-04:
(9*1)+(8*1)+(7*7)+(6*4)+(5*3)+(4*9)+(3*8)+(2*0)+(1*4)=169
169 % 10 = 9
So 1174398-04-9 is a valid CAS Registry Number.
