Check Digit Verification of cas no

The CAS Registry Mumber 1888-38-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,8 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1888-38:
(6*1)+(5*8)+(4*8)+(3*8)+(2*3)+(1*8)=116
116 % 10 = 6
So 1888-38-6 is a valid CAS Registry Number.

Silver-Catalyzed Coupling of Two Csp3-H Groups and One-Pot Synthesis of Tetrasubstituted Furans, Thiophenes, and Pyrroles

Mao, Shuai,Zhu, Xue-Qing,Gao, Ya-Ru,Guo, Dong-Dong,Wang, Yong-Qiang

supporting information, p. 11335 - 11339 (2015/08/03)

Silver-catalyzed coupling of two Csp3-H groups to form 1,4-diketones have been developed for the first time. The resultant ketones then undergo cyclization to synthesize tetrasubstituted furans, thiophenes, and pyrroles from benzyl ketone derivatives in a one-pot reaction process. This highly-efficient synthetic method, which utilizes air as the terminal oxidant and readily accessible starting materials, displays a wide substrate scope and broad functional-group tolerance.

Copper(II)-promoted C-C bond formation by oxidative coupling of two C(sp3)-H bonds adjacent to carbonyl group to construct 1,4-diketones and tetrasubstituted furans

Mao, Shuai,Gao, Ya-Ru,Zhang, Shao-Liang,Guo, Dong-Dong,Wang, Yong-Qiang

, p. 876 - 885 (2015/01/30)

The copper(II)-promoted C-C bond formation from the coupling of two C(sp3)-H bonds that are adjacent to a carbonyl group was achieved. This protocol offers a simple and efficient approach to 2,3-disubstituted 1,4-diketones and tetrasubstituted furans. This method features a wide substrate scope and high functional group tolerance.
