Check Digit Verification of cas no

The CAS Registry Mumber 21855-82-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,5 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21855-82:
(7*2)+(6*1)+(5*8)+(4*5)+(3*5)+(2*8)+(1*2)=113
113 % 10 = 3
So 21855-82-3 is a valid CAS Registry Number.

Conversion of Carbonyl Compounds to Olefins via Enolate Intermediate

Cao, Zhi-Chao,Xu, Pei-Lin,Luo, Qin-Yu,Li, Xiao-Lei,Yu, Da-Gang,Fang, Huayi,Shi, Zhang-Jie

supporting information, p. 781 - 785 (2019/06/24)

A general and efficient protocol to synthesize substituted olefins from carbonyl compounds via nickel catalyzed C—O activation of enolates was developed. Besides ketones, aldehydes were also suitable substrates for the presented catalytic system to produce di- or tri- substituted olefins. It is worth noting that this approach exhibited good tolerance to highly reactive tertiary alcohols, which could not survive in other reported routes for converting carbonyl compounds to olefins. This method also showed good regio- and stereo-selectivity for olefin products. Preliminary mechanistic studies indicated that the reaction was accomplished through nickel catalyzed C—O activation of enolates, thus offering helpful contribution to current enol chemistry.

Atom-efficient vinylic arylations with triarylbismuths as substoichiometric multicoupling reagents under palladium catalysis

Rao, Maddali L.N.,Jadhav, Deepak N.,Venkatesh, Varadhachari

experimental part, p. 4300 - 4306 (2011/02/24)

The first atom-efficient arylation of vinylic iodides was achieved by using triarylbismuths as substoichiometric multicoupling reagents under palladium catalysis. Vinylic iodides were efficiently coupled with electronically divergent triarylbismuths to furnish the corresponding arylated products in short reaction times.
