Check Digit Verification of cas no

The CAS Registry Mumber 1201221-02-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,1,2,2 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1201221-02:
(9*1)+(8*2)+(7*0)+(6*1)+(5*2)+(4*2)+(3*1)+(2*0)+(1*2)=54
54 % 10 = 4
So 1201221-02-4 is a valid CAS Registry Number.

De novo synthesis of functionalized 1,3-enynes and extended conjugated molecular systems

Rao, Maddali L. N.,Dasgupta, Priyabrata,Murty, Venneti N.

, p. 24834 - 24845 (2015/03/30)

Pd-catalyzed coupling of 1,3-dienyldibromides with triarylbismuths was demonstrated for the synthesis of a diverse range of 1,3-enynes. This study provided easy access to a range of functionalized 1,3-enynes in high yields utilizing triarylbismuths in sub

Highly regio- and stereoselective synthesis of 1,3-enynes from unactivated ethylenes via palladium-catalyzed cross-coupling

Wen, Yanmei,Wang, Azhong,Jiang, Huanfeng,Zhu, Shifa,Huang, Liangbin

supporting information; experimental part, p. 5736 - 5739 (2011/12/03)

An efficient procedure for regio- and stereoselective synthesis of a series of conjugated enynes by a simple Pd-catalyzed cross-coupling reaction of unactivated ethylenes and ethynyl bromide has been developed. The reaction proceeds smoothly in DMF to give the corresponding products in good to excellent yields. The protocol can tolerate a broad range of functional groups on the substrates.

Palladium-free synthesis of conjugated enynes by direct olefination of terminal alkynes using vinyl bromides

Liu, Yunyun,Yang, Jianguo,Bao, Weiliang

experimental part, p. 5317 - 5320 (2010/02/27)

A series of conjugated enynes were successfully synthesized by the direct copper-catalyzed coupling reaction of vinyl bromides and alkynes. The reaction proceeds smoothly in DMF at 110 °C to give the corresponding products in good to excellent yields. The protocol is tolerant to a broad range of functional groups on the substrates. Moreover, the products were furnished as specific E isomers, as the stereochemistry of the vinyl bromides was retained.
