140836-74-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140836-74-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,3 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 140836-74:
(8*1)+(7*4)+(6*0)+(5*8)+(4*3)+(3*6)+(2*7)+(1*4)=124
124 % 10 = 4
So 140836-74-4 is a valid CAS Registry Number.

Synthesis and optical resolution of an antiallergic agent KW4099 with thromboxane A2 antigonistic activity
Sugaya,Kuge,Tomioka,Tamaki
, p. 238 - 239 (2007/10/02)
A new antiallergic agent with thromboxane A2 antagonistic activity, KW4099, was synthesized by a simple method. Its optical resolution was accomplished with the use of (+)- or (-)-2,2'-(1,1'-binaphthyl)phosphoric acid as a resolving agent.
