590419-34-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 590419-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,9,0,4,1 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 590419-34:
(8*5)+(7*9)+(6*0)+(5*4)+(4*1)+(3*9)+(2*3)+(1*4)=164
164 % 10 = 4
So 590419-34-4 is a valid CAS Registry Number.
