Check Digit Verification of cas no

The CAS Registry Mumber 1638643-98-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,8,6,4 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1638643-98:
(9*1)+(8*6)+(7*3)+(6*8)+(5*6)+(4*4)+(3*3)+(2*9)+(1*8)=207
207 % 10 = 7
So 1638643-98-7 is a valid CAS Registry Number.

Synthesis of N-substituted (Z)-3-arylbenzo[c]thiophen1(3H)-imines by the reaction of 1-[aryl(methoxy)methyl]2-lithiobenzenes with isothiocyanates followed by acid-mediated cyclization

Kobayashi, Kazuhiro,Shigemura, Yuuho,Ezaki, Kosuke

, p. 526 - 536 (2015)

A simple procedure for the preparation of N-substituted (Z)-3-arylbenzo [c]thiophen-1(3H)-imines has been developed. Thus, bromine/lithium exchange between 1-[aryl(methoxy)methyl]-2-bromobenzenes and butyllithium, followed by reaction of the resulting 1-[

Synthesis of substituted biaryls through gold-catalyzed petasis-ferrier rearrangement of propargyl ethers

Pati, Kamalkishore,Alabugin, Igor V.

supporting information, p. 3986 - 3990 (2014/07/08)

Au-catalyzed cycloisomerization of aryl propargyl ethers provides controlled transition from alkyne to carbonyl chemistry followed up by a Petasis-Ferrier rearrangement/aromatization cascade leading to substituted biaryls with functionalized naphthalene cores. An Au-catalyzed sequence of alkoxy group translocation, Petasis-Ferrier rearrangement, and aromatization transforms aryl propargyl ethers into substituted biaryls with functionalized naphthalene cores.
