1884-86-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1884-86-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,8 and 4 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1884-86:
(6*1)+(5*8)+(4*8)+(3*4)+(2*8)+(1*6)=112
112 % 10 = 2
So 1884-86-2 is a valid CAS Registry Number.

2-amino-1-phenyl-propan-1,3-diol as chiral auxiliary. Application in the synthesis of cis 3-phthalimido-4-styryl-2-azetidinones

Gunda, Tamas E.,Sztaricskai, Ferenc

, p. 7985 - 7998 (2007/10/03)

3,4-cis3,4-cis-1-N-(1'-phenyl-1',3'-dihydroxy-2'-propyl)-3-phthalimido-4 -styrylazetidinones were obtained in optically pure form by chiral Staudinger reaction. The cis-α/β-ratio could be influenced by the protective groups of the diol moiety. Removal of the chiral auxiliarity could be accomplished by direct oxidation, or by previous double bond formation, thus the 2-amino-1-phenyl-propan-1,3-diol can be regarded to a generally useful chiral auxiliary.
