118830-56-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118830-56-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,8,3 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 118830-56:
(8*1)+(7*1)+(6*8)+(5*8)+(4*3)+(3*0)+(2*5)+(1*6)=131
131 % 10 = 1
So 118830-56-1 is a valid CAS Registry Number.

, p. 801 - 805 (2007/10/03)
Like barbituric acid, 2-thiobarbituric acid with aromatic aldehydes in pyridine forms pyridinium salts of 5,5′-arylmethylenebis(2-thiobarbituric acids). These salts can be isolated when the aldehyde contains both electron-acceptor and electron-donor subst
