1609184-04-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1609184-04-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,1,8 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1609184-04:
(9*1)+(8*6)+(7*0)+(6*9)+(5*1)+(4*8)+(3*4)+(2*0)+(1*4)=164
164 % 10 = 4
So 1609184-04-4 is a valid CAS Registry Number.
