Check Digit Verification of cas no

The CAS Registry Mumber 188777-47-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,7,7 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 188777-47:
(8*1)+(7*8)+(6*8)+(5*7)+(4*7)+(3*7)+(2*4)+(1*7)=211
211 % 10 = 1
So 188777-47-1 is a valid CAS Registry Number.

Electrophilic Amination of Amino Acids with N-Boc-oxaziridines: Efficient Preparation of N-Orthogonally Diprotected Hydrazino Acids and Piperazic Acid Derivatives

Hannachi, Jean-Christophe,Vidal, Joelle,Mulatier, Jean-Christophe,Collet, Andre

, p. 2367 - 2373 (2007/10/03)

A general two-step preparation of enantiopure Nα,N β-orthogonally diprotected α-hydrazino acids 1 is developed on a multigram scale. The key reaction is the efficient electrophilic amination of N-benzyl amino acids 6 with N-Boc-oxaziridine 7 and accommodates various functional groups encountered in side chains of amino acids. The cyclic 2,3,4,5-tetrahydro-3-pyridazine carboxylic acid (piperazic acid) derivatives 2 and 3 or the cyclic 3,4-dihydro-3-pyrazolecarboxylate 4 are conveniently prepared from glutamic acid or aspartic acid via orthogonally diprotected α-hydrazino acids 1m and 1n.
