Check Digit Verification of cas no

The CAS Registry Mumber 139255-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,5 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139255-91:
(8*1)+(7*3)+(6*9)+(5*2)+(4*5)+(3*5)+(2*9)+(1*1)=147
147 % 10 = 7
So 139255-91-7 is a valid CAS Registry Number.

New chiral auxiliaries based on conformation control, a C2-symmetric 2,2-dimethylimidazolidine and 4-chiral 2,2-dialkyloxazolidines. Synthesis and conformational analysis of acrylamide derivatives

Kanemasa,Onimura

, p. 8631 - 8644 (2007/10/02)

New chirality-controlling auxiliaries, a C2-symmetric 2,2-dimethylimidazolidine and 4-chiral 2,2-dialkyloxazolidines, are readily prepared from a C2-symmetric 1,2-ethanediamine and naturally occurring α-amino acids, respectively. Con

2,2-dimethyl-4-phenyloxazolidine and 2,2-dimethyl-4,5-diphenylimidazolidine as new chiral auxiliaries. Applications to asymmetric nitrile oxide cycloadditions

Kanemasa,Onimura,Wada,Tanaka

, p. 1185 - 1188 (2007/10/02)

Asymmetric dipolar cycloadditions of a nitrile oxide to the acrylamide derivatives of two new chiral auxiliaries, (R)-2,2-dimethyl-4-phenyloxazolidines and (S,S)-2,2-dimethyl-4,5-diphenylimidazolidine, show satisfactorily high diastereoselectivities (up to 91%).
