18019-58-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18019-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,0,1 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 18019-58:
(7*1)+(6*8)+(5*0)+(4*1)+(3*9)+(2*5)+(1*8)=104
104 % 10 = 4
So 18019-58-4 is a valid CAS Registry Number.
