207223-31-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 207223-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,2,2 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 207223-31:
(8*2)+(7*0)+(6*7)+(5*2)+(4*2)+(3*3)+(2*3)+(1*1)=92
92 % 10 = 2
So 207223-31-2 is a valid CAS Registry Number.

Stereoselective synthesis of α-hydroxycyclopropanecarboxylic acids
Pansare, Sunil V.,Jain, Rajendra P.
, p. 2625 - 2628 (2007/10/03)
Cyclopropanation of chiral α-alkoxy acrylamides derived from 1R,2S- ephedrine and α-keto acids provides cyclopropyl morpholinones with good diastereoselectivity. Removal of the ephedrine portion generates α- hydroxycyclopropane carboxamides which are read
