Check Digit Verification of cas no

The CAS Registry Mumber 127583-42-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,5,8 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 127583-42:
(8*1)+(7*2)+(6*7)+(5*5)+(4*8)+(3*3)+(2*4)+(1*2)=140
140 % 10 = 0
So 127583-42-0 is a valid CAS Registry Number.

Highly enantiomeric purity conversion of α-sulfinyl oximes and α-sulfinyl hydrazones to the corresponding β-keto sulfoxides with butyltriphenylphosphonium periodate (BUTPPPI)

Hajipour,Ruoho

, p. 2653 - 2657 (2007/10/03)

Butyltriphenylphosphonium periodate (Ph3P+BuIO 4-)1 is readily prepared as a white solid from butyltriphenylphosphonium chloride, performs conversion of α-sulfinyl oximes (2) and α-sulfinyl hydrazones (4) to the

Enantioselective oxidation of sulphides to sulphoxides in the presence of bovine serum albumin

Colonna,Gaggero,Leone,Pasta

, p. 8385 - 8398 (2007/10/02)

In situ generated dioxiranes oxidize a series of prochiral sulphides to the corresponding sulphoxides with enantiomeric excess (e.e.) up to 89%, when bovine serum albumin (BSA) is used as chiral auxiliary. The degree of enantioselectivity, as well as yield and reaction times, depend upon the nature of the dioxirane. These are compared with enantioselectivities attainable for the same transformations by using peroxomonosulfate alone, i.e. in the absence of ketone. In the oxidation of prochiral keto sulphides (wherein the carbonyl functionality serves as precursor of dioxirane) with peroxomonosulfate, optically active keto sulphoxides are isolated in satisfactory chemical and optical yield (up to e.e. 84%).
