Check Digit Verification of cas no

The CAS Registry Mumber 118540-56-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,5,4 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 118540-56:
(8*1)+(7*1)+(6*8)+(5*5)+(4*4)+(3*0)+(2*5)+(1*6)=120
120 % 10 = 0
So 118540-56-0 is a valid CAS Registry Number.

Isocyanide-based MCRs: Diastereoselective cascade synthesis of perfluoroalkylated pyrano[3,4-c]pyrrole derivatives

Yang, Shanxue,Yao, Lan,Fan, Zhenhua,Han, Jing,Chen, Jie,He, Weimin,Deng, Hongmei,Shao, Min,Zhang, Hui,Cao, Weiguo

, (2021)

The highly diastereoselective synthesis of perfluoroalkyl-containing pyrano[3,4-c]pyrroles has been accomplished via a cascade process involving Michael addition, Passerini-type reaction, Mumm rearrangement and an oxo-Diels–Alder reaction. This domino tra

Metal-free reduction of unsaturated carbonyls, quinones, and pyridinium salts with tetrahydroxydiboron/water

Li, Tiejun,Peng, Henian,Tang, Wenjun,Tian, Duanshuai,Xu, Guangqing,Yang, He

, p. 4327 - 4337 (2021/05/31)

A series of unsaturated carbonyls, quinones, and pyridinium salts have been effectively reduced to the corresponding saturated carbonyls, dihydroxybenzenes, and hydropyridines in moderate to high yields with tetrahydroxydiboron/water as a mild, convenient, and metal-free reduction system. Deuterium-labeling experiments have revealed this protocol to be an exclusive transfer hydrogenation process from water. This journal is

Hydrogen-bond-directed formal [5 + 1] annulations of oxindoles with ester-linked bisenones: Facile access to chiral spirooxindole δ-lactones

Zhao, Shuai,Lin, Jun-Bing,Zhao, Yuan-Yuan,Liang, Yong-Min,Xu, Peng-Fei

supporting information, p. 1802 - 1805 (2014/04/17)

A novel bifunctional thiourea catalyzed formal [5 + 1] cycloaddition of oxindoles and ester-linked bisenones was successfully developed. This strategy involves two sequential Michael additions, leading to spirooxindole δ-lactones with three contiguous ste
