Calculate Digit Verification of CAS Registry Number 191927-02:
(8*1)+(7*9)+(6*1)+(5*9)+(4*2)+(3*7)+(2*0)+(1*2)=153
153 % 10 = 3
So 191927-02-3 is a valid CAS Registry Number.

Dialkynylation of aryl aldehydes using dialkynylboron chlorides: A transition-metal-free route to 1,4-diynes

Yao, Min-Liang,Pippin, Adam B.,Wu, Zhong-Zhi,Quinn, Michael P.,Li, Yong,Reddy, Marepally S.,Kabalka, George W.

, p. 164 - 166 (2012)

Dialkynylboron chlorides couple smoothly with aryl aldehydes at room temperature to afford 1,4-dialkynes in good to excellent yields. Dialkynylboron halides act simultaneously as Lewis acid and reactant in this coupling reaction.
