582321-75-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 582321-75-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,8,2,3,2 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 582321-75:
(8*5)+(7*8)+(6*2)+(5*3)+(4*2)+(3*1)+(2*7)+(1*5)=153
153 % 10 = 3
So 582321-75-3 is a valid CAS Registry Number.
