Check Digit Verification of cas no

The CAS Registry Mumber 1167412-36-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,7,4,1 and 2 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1167412-36:
(9*1)+(8*1)+(7*6)+(6*7)+(5*4)+(4*1)+(3*2)+(2*3)+(1*6)=143
143 % 10 = 3
So 1167412-36-3 is a valid CAS Registry Number.

Synthesis of Thiazinoimidazoles by Lewis Acid–Catalyzed [3+3] Cycloaddition Reactions of Propargyl Alcohols with 2-Mercaptoimidazoles

Mishima, Naoya,Ogawa, Takahiro,Tanabe, Genzoh,Muraoka, Osamu,Wasada, Hiroaki,Hatae, Noriyuki,Yoshimatsu, Mitsuhiro

supporting information, p. 3117 - 3121 (2019/05/29)

The unique ytterbium-catalyzed generation of sulfur- and selenium-substituted propargylic and allenic cations and their reactions with 2-mercaptoimidazole derivatives were described. The regioselective [3+3] annulation reactions proceeded to give a wide variety of S,N-acetal-containing bicyclic and tricyclic thiazinoimidazoles in good to high yields. Treatment of thiazinoimidazoles with LDA readily underwent ring contraction to afford thiazolobenzimidazoles. Deselenenylation and successive functionalization broaden the scope of accessible thiazinoimidazoles.
