Check Digit Verification of cas no

The CAS Registry Mumber 1210054-37-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,0,0,5 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1210054-37:
(9*1)+(8*2)+(7*1)+(6*0)+(5*0)+(4*5)+(3*4)+(2*3)+(1*7)=77
77 % 10 = 7
So 1210054-37-7 is a valid CAS Registry Number.

Domino C?S/C?N Bond Formation Using Well-Defined Copper-Phosphine Complex Catalyst: Divergent Approach to 3-Sulfenylated Indoles

Tamargo, Ramuel John Inductivo,Kim, Sung Hong,Lee, Yong Rok

, p. 4005 - 4015 (2019/07/18)

A protocol was developed for the synthesis of 3-thioindoles in good-to-excellent yields involving sulfenylation between 2-nitrocinnamaldehydes and various thiols using a well-defined copper(I)-phosphine complex catalyst. This unconventional divergent approach involves in situ generation of indoles via domino C?S/C?N bond formation initiated by sulfa-Michael addition followed by intramolecular N-heteroannulation. This protocol shows good chemoselectivity and broad substrate scope. To briefly demonstrate the value of this approach, 2-benzoyl-3-sulfenylated indoles were prepared from commercially available 2-nitrochalcones and thiols. (Figure presented.).

Iron-catalyzed sulfenylation of indoles with disulfides promoted by a catalytic amount of iodine

Fang, Xiao-Li,Tang, Ri-Yuan,Zhong, Ping,Li, Jin-Heng

experimental part, p. 4183 - 4189 (2011/02/28)

Selective sulfenylation of indoles with disulfides using iron(III) fluoride combined with iodine has been developed for the synthesis of sulfenylindoles. In the presence of iron(III) fluoride and iodine, a variety of disulfides underwent the reaction with indoles selectively to afford the corresponding sulfenylindoles in good to excellent yields. Moreover, reactions of indoles with 1,2-diphenyldiselane were also conducted under the same conditions, which smoothly afforded 3-selenylindoles in good yields.
