1589-18-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1589-18-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,8 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1589-18:
(6*1)+(5*5)+(4*8)+(3*9)+(2*1)+(1*8)=100
100 % 10 = 0
So 1589-18-0 is a valid CAS Registry Number.
