1023287-35-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1023287-35-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,3,2,8 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1023287-35:
(9*1)+(8*0)+(7*2)+(6*3)+(5*2)+(4*8)+(3*7)+(2*3)+(1*5)=115
115 % 10 = 5
So 1023287-35-5 is a valid CAS Registry Number.

Cooperative, highly enantioselective phosphinothiourea catalysis of imine - Allene [3 + 2] cycloadditions
Fang, Yuan-Qing,Jacobsen, Eric N.
, p. 5660 - 5661 (2008/12/21)
A new family of phosphinthiourea catalysts was developed for the highly enantioselective synthesis of 2-aryl-2,5-hydropyrroles via a [3 + 2] cycloaddition of an electron-deficient allene with aryl and heteroaryl diphenylphosphinoylimines. The presence of
