Check Digit Verification of cas no

The CAS Registry Mumber 1027804-05-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,8,0 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1027804-05:
(9*1)+(8*0)+(7*2)+(6*7)+(5*8)+(4*0)+(3*4)+(2*0)+(1*5)=122
122 % 10 = 2
So 1027804-05-2 is a valid CAS Registry Number.

Stereospecific Iron-Catalyzed Carbon (sp2)-Carbon (sp2) Cross-Coupling of Aryllithium with Vinyl Halides

Chen, Peng,Peng, Xiao-Shui,Wang, Zhi-Yong,Wong, Henry N. C.

, p. 4385 - 4390 (2021)

We present herein an efficient synthetic protocol involving iron-catalyzed cross-coupling of organolithium compounds with vinyl halides as key coupling partners. More than 30 examples were obtained with moderate to good yields and high stereoselectivities. The practicality of this method is evidenced by a gram-scale synthesis. In addition, a preliminary mechanistic investigation was also performed.
