112519-51-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112519-51-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,5,1 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 112519-51:
(8*1)+(7*1)+(6*2)+(5*5)+(4*1)+(3*9)+(2*5)+(1*1)=94
94 % 10 = 4
So 112519-51-4 is a valid CAS Registry Number.

The Synthesis of 4-Hydroxydithiocoumarins: A Case of Unusual Tautomer Stability
Anderson-McKay, Janet E.,Liepa, Andris J.
, p. 1179 - 1190 (2007/10/02)
2'-Chloroacetophenones react with carbon disulfide in the presence of sodium hydride to form 4-hydroxydithiocoumarin anions.Kinetic protonation provides the 4-hydroxydithiocoumarins which can be tautomerized to 2-mercapto-1-thiochromones by treatment with
