Check Digit Verification of cas no

The CAS Registry Mumber 171227-49-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,2,2 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 171227-49:
(8*1)+(7*7)+(6*1)+(5*2)+(4*2)+(3*7)+(2*4)+(1*9)=119
119 % 10 = 9
So 171227-49-9 is a valid CAS Registry Number.

Facile asymmetric synthesis of aziridine derivatives via the diastereoselective reaction of chiral imines with dimethylsulfonium methylide

Higashiyama, Kimio,Matsumura, Masataka,Shiogama, Ayako,Yamauchi, Takayasu,Ohmiya, Sigeru

, p. 85 - 88 (2007/10/03)

A simple method for the synthesis of chiral 2-substituted aziridine derivatives is described. The reaction pathway consists of the diastereoselective addition of dimethylsulfonium methylide to chiral imines derived from (R)-phenylglycinol and various aldehydes.

Diastereoselective addition of chiral aliphatic imines and 2-alkyl-1,3-oxazolidines to organometallic reagents

Higashiyama,Fujikura,Takahashi

, p. 722 - 728 (2007/10/02)

The reaction of organocerium reagents with chiral aliphatic imines derived from (R)-O-methylphenylglycinol afforded the corresponding amines with high diastereoselectivity. In contrast, the reaction of Grignard reagents with chiral 2-alkyl-1,3-oxazolidines derived from (R)-N-methylphenylglycinol afforded the amines with changeover in diastereoselectivity.
