Check Digit Verification of cas no

The CAS Registry Mumber 1017238-70-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,7,2,3 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1017238-70:
(9*1)+(8*0)+(7*1)+(6*7)+(5*2)+(4*3)+(3*8)+(2*7)+(1*0)=118
118 % 10 = 8
So 1017238-70-8 is a valid CAS Registry Number.

Metal-Free Cross-Coupling of Arylboronic Acids and Derivatives with DAST-Type Reagents for Direct Access to Diverse Aromatic Sulfinamides and Sulfonamides

Wang, Qiang,Tang, Xiang-Ying,Shi, Min

, p. 10811 - 10815 (2016)

We have developed a simple and convenient method for the cross-coupling of arylboronic acids and their derivatives with DAST-type reagents under mild and metal-free conditions to directly afford sulfinamides in moderate to good yields. Moreover, sulfonamides were obtained after a simple oxidation reaction. The reaction mechanism was investigated by18O-labeling experiments, and the synthetic utility was demonstrated by the sulfoxidation of natural products.

Fast and efficient synthesis of sulfinamides by the oxidation of sulfenamides using potassium fluoride and m-chloroperoxybenzoic acid

Datta, Mrityunjoy,Buglass, Alan J.

experimental part, p. 1760 - 1769 (2012/05/04)

A procedure for the synthesis of N-alkyl-, N-cycloalkyl-, N,N-dialkyl-, and N-arylarenesulfinamides from the corresponding sulfenamides using KF/m-chloroperoxybenzoic acid (CPBA) in CH3CN-H2O is described. High efficiency (fast react

Mild and general method for the synthesis of sulfonamides

Garcia Ruano, Jose Luis,Parra, Alejandro,Yuste, Francisco,Mastranzo, Virginia M.

, p. 311 - 319 (2008/12/22)

Reaction of methyl sulfinates with lithium amides followed by 3-chloroperoxybenzoic acid oxidation of the resulting sulfinamides provides primary, secondary, and tertiary alkane-, arene-and heteroarenesulfonamides in high yields. This constitutes a mild and facile experimental protocol that avoids the use of hazardous, unstable, or volatile reagents and does not affect the configurational stability of the amines.
