290811-67-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 290811-67-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,0,8,1 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 290811-67:
(8*2)+(7*9)+(6*0)+(5*8)+(4*1)+(3*1)+(2*6)+(1*7)=145
145 % 10 = 5
So 290811-67-5 is a valid CAS Registry Number.

α-(4-Nitro Phenoxy) chalcones as synthons for cis-(±)-1,5- benzothiazepines
Rao,Arun Kumar Gupta,Gupta
, p. 2763 - 2768 (2007/10/03)
α-(4-Nitro Phenoxy) chalcones, V have been utilized as intermediate for the synthesis of some new cis- (±)-2-aryl-3-(4-nitro phenoxy)-4-phenyl-1,5- benzothiazepine VI by cycloconden-sation of 2-amino thiophenol in the presence of mild base.
