1191415-24-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1191415-24-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,1,4,1 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1191415-24:
(9*1)+(8*1)+(7*9)+(6*1)+(5*4)+(4*1)+(3*5)+(2*2)+(1*4)=133
133 % 10 = 3
So 1191415-24-3 is a valid CAS Registry Number.

Palladium-Catalyzed Domino Cyclization/Phosphorylation of gem-Dibromoolefins with P(O)H Compounds: Synthesis of Phosphorylated Heteroaromatics

Chen, Chen,Ding, Jie,Liu, Liying,Huang, Yujie,Zhu, Bolin

, p. 200 - 205 (2021/10/29)

We presented a palladium-catalyzed domino cyclization/phosphorylation of gem-dibromoolefins, which utilize H-phosphinates and secondary phosphine oxides as the phosphine sources, respectively. A variety of phosphorylated heteroaromatics were obtained in m
