334769-57-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 334769-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,4,7,6 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 334769-57:
(8*3)+(7*3)+(6*4)+(5*7)+(4*6)+(3*9)+(2*5)+(1*7)=172
172 % 10 = 2
So 334769-57-2 is a valid CAS Registry Number.

Scope and limitations in the use of N-(PhF)serine-derived cyclic sulfamidates for amino acid synthesis
Wei,Lubell
, p. 94 - 104 (2007/10/03)
Ring-opening of N-(PhF)serine-derived cyclic sulfamidate 17 was achieved with different nucleophiles (βketo esters, β-keto ketones, dimethyl malonate, nitroethane, sodium azide, imidazole, and potassium thiocyanate) to prepare a variety of amino acid anal
