Check Digit Verification of cas no

The CAS Registry Mumber 211811-93-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,8,1 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 211811-93:
(8*2)+(7*1)+(6*1)+(5*8)+(4*1)+(3*1)+(2*9)+(1*3)=97
97 % 10 = 7
So 211811-93-7 is a valid CAS Registry Number.

Asymmetric synthesis of unnatural amino acids and tamsulosin chiral intermediate

Arava, Veera Reddy,Amasa, Srinivasulu Reddy,Goud Bhatthula, Bharat Kumar,Kompella, Laxmi Srinivas,Matta, Venkata Prasad,Subha

, p. 2892 - 2897 (2013/09/02)

An efficient and enantioselective hydrogenation of N-acetylamino phenyl acrylic acids was successfully developed by using ruthenium catalyst. This methodology is important in the field of pharmaceuticals and provides a new process for the preparation of unnatural amino acids and tamsulosin chiral intermediate.

BIOCATALYTICAL TRANSFORMATIONS II. ENANTIOSELECTIVE HYDROLYSIS OF N-ACETYL-FLUORO-PHENYLALANINE-ETHYLESTERS BY LYOPHILISED YEAST

Csuk, Rene,Glaenzer, Brigitte I.

, p. 99 - 106 (2007/10/02)

The three nuclear substituted monofluoro D-N-acetylphenylalanine-ethylesters were obtained in excellent yield via enantioselective hydrolysis of their respective racemates by use of lyophilised yeast (Saccharomyces cerevisiae Hansen).
