Check Digit Verification of cas no

The CAS Registry Mumber 144989-61-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,9,8 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 144989-61:
(8*1)+(7*4)+(6*4)+(5*9)+(4*8)+(3*9)+(2*6)+(1*1)=177
177 % 10 = 7
So 144989-61-7 is a valid CAS Registry Number.

A General Route to the Synthesis of N-Protected 1-Substituted and 1,2-Disubstituted Taurines

Xu, Jiaxi,Xu, Shu

, p. 276 - 282 (2007/10/03)

N-Benzyloxycarbonyl protected α-substituted and αβ- disubstituted taurines were synthesized from olefins and epoxides via N-benzyloxycarbonylamino alcohol thioacetates as key intermediates. They are important sulfur analogues of naturally occurring amino acids and building blocks for the synthesis of α-substituted and α,β- disubstituted β-sulfonopeptides.

An Enantiospecific Synthesis of Allosamizoline

Simpkins, Nigel S.,Stokes, Stephen,Whittle, Alan J.

, p. 2471 - 2478 (2007/10/02)

An enantiospecific synthesis of allosamizoline 4, the aglycone of the chitinase inhibitor allosamidin 3, has been achieved, starting from readily available glucosamine.The key step in the synthesis involves the cyclisation of a carbon-centred radical onto
