119023-40-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119023-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,0,2 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 119023-40:
(8*1)+(7*1)+(6*9)+(5*0)+(4*2)+(3*3)+(2*4)+(1*0)=94
94 % 10 = 4
So 119023-40-4 is a valid CAS Registry Number.

Synthesis and Structure of Some Thiazole Derivatives
Badawy, Mohammed A.,Abdel-Hady, Sayed A.,Ibrahim, Yehia A.
, p. 393 - 395 (2007/10/02)
The addition of thiosemicarbazones 1 to α-halo acids 2 is shown to give 2-hydrazino-2-thiazolin-4-ones 3 and not 3-substituted 2-imino-3-(methyleneimino)thiazolidin-4-ones 4.The independent synthesis of 2-thiazolin-4-one derivatives 3 is also described.
