Check Digit Verification of cas no

The CAS Registry Mumber 117839-39-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,8,3 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 117839-39:
(8*1)+(7*1)+(6*7)+(5*8)+(4*3)+(3*9)+(2*3)+(1*9)=151
151 % 10 = 1
So 117839-39-1 is a valid CAS Registry Number.

Facile synthesis of substituted quinolines by iron(iii)-catalyzed cascade reaction between anilines, aldehydes and nitroalkanes

Mahato, Sachinta,Mukherjee, Anindita,Santra, Sougata,Zyryanov, Grigory V.,Majee, Adinath

, p. 7907 - 7917 (2019/09/06)

A library of substituted quinolines has been synthesized by the reaction of aldehydes, anilines and nitroalkanes using a catalytic amount of Fe(iii) chloride. The reaction is a simple, efficient, one-pot, three-component domino strategy in ambient air which afforded the products in high yields. A probable pathway of the reaction is a sequential aza-Henry reaction/cyclization/denitration. The use of commercially available chemicals as starting materials, an inexpensive metal catalyst, aerobic reaction conditions, tolerance of a wide range of functional groups, and operational simplicity are the notable advantages of this present protocol.

Approaches to a photocleavable protecting group for alcohols

Epling, Gary A.,Provatas, Anthony A.

, p. 1036 - 1037 (2007/10/03)

A new protecting group for the alcohol functionality was devised and shown to be removed photochemically under ultraviolet light in the presence of a radical scavenger in high yields.

A NEW PHOTOCHEMICALLY REMOVABLE PROTECTING GROUP FOR AMINES

Epling, Gary A.,Walker, Mary E.

, p. 3843 - 3846 (2007/10/02)

A new arylmethylsulfonyl chloride reacts with secondary or primary amines to give sulfonamides which can be photochemically cleaved, making it suitable for use as a photoremovable protecting group.
