184370-65-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 184370-65-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,4,3,7 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 184370-65:
(8*1)+(7*8)+(6*4)+(5*3)+(4*7)+(3*0)+(2*6)+(1*5)=148
148 % 10 = 8
So 184370-65-8 is a valid CAS Registry Number.

N -Alkynyl Pyrrole Based Total Synthesis of Shensongine A

Kerwin, Sean M.,Reinus, Brandon J.

, p. 4085 - 4105 (2019/10/28)

A copper-catalyzed N-alkynylation of pyrrole and a gold-catalyzed spiroketalization were key steps in the total synthesis of the pyrrole spiroketal alkaloid shensongine A. The preparation of this alkaloid is concise and amenable to the rapid synthesis of

Efficient synthesis of monosubstituted 3-alkynylfurans via Suzuki coupling

Yang, Xiaobao,Zhu, Li,Zhou, Yuedong,Li, Zhong,Zhai, Hongbin

, p. 1729 - 1732 (2008/12/22)

A convenient synthesis of monosubstituted 3-alkynyl-furans by Suzuki coupling reaction of 3-furanylboronic acid with substituted acetylene bromides is described. The internal alkyne products were attainable in 50-89% yields from substrates free of relatively acidic protons. Our protocol is expected to find applications in the synthesis of structurally related natural products.
