Check Digit Verification of cas no
The CAS Registry Mumber 125611-76-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,6,1 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 125611-76:
(8*1)+(7*2)+(6*5)+(5*6)+(4*1)+(3*1)+(2*7)+(1*6)=109
109 % 10 = 9
So 125611-76-9 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.
