Check Digit Verification of cas no

The CAS Registry Mumber 1356012-59-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,6,0,1 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1356012-59:
(9*1)+(8*3)+(7*5)+(6*6)+(5*0)+(4*1)+(3*2)+(2*5)+(1*9)=133
133 % 10 = 3
So 1356012-59-3 is a valid CAS Registry Number.

Synthesis of Functionalized α-Vinyl Aldehydes from Enaminones

Chen, Jie,Guo, Pan,Zhang, Jianguo,Rong, Jiaxin,Sun, Wangbin,Jiang, Yaojia,Loh, Teck-Peng

, p. 12674 - 12679 (2019/08/07)

An efficient RhII-catalyzed synthesis of functionalized α-vinyl aldehydes with high E/Z stereoselectivity was developed. The reaction mediates the cyclopropanation of enaminones with vinyl carbenoids that are generated from cyclopropenes in situ to give the aminocyclopropane intermediates. Selective C?C bond cleavage of the cyclopropane intermediates leads to formation of α-vinyl aldehyde derivatives with high E/Z selectivity. This method proceeds at room temperature under very mild reaction conditions and works with a broad substrate scope.

Divergent outcomes of gold(I)-catalyzed indole additions to 3,3-disubstituted cyclopropenes

Young, Paul C.,Hadfield, Maximillian S.,Arrowsmith, Lynn,MacLeod, Kristina M.,Mudd, Richard J.,Jordan-Hore, James A.,Lee, Ai-Lan

, p. 898 - 901 (2012/04/18)

Depending on the conditions employed, gold(I)-catalyzed addition of indoles to 3,3-disubstituted cyclopropenes can be controlled to yield either 3-(E)-vinylindoles (3) or bis-indolylalkanes (4). If the cyclopropene substituents are sterically bulky, unprecedented gold-catalyzed oxidation under air occurs to yield bis-indolylalkene (5) and epoxide (6) at room temperature.
