1240643-67-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1240643-67-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,6,4 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1240643-67:
(9*1)+(8*2)+(7*4)+(6*0)+(5*6)+(4*4)+(3*3)+(2*6)+(1*7)=127
127 % 10 = 7
So 1240643-67-7 is a valid CAS Registry Number.

A mild and efficient method for bromination of alcohols using α,α-dibromo-β-dicarbonyl compounds as halogen sources

Cui, Xiao-Meng,Guan, Yong-Hong,Li, Na,Lv, Hao,Fu, Lin-An,Guo, Kun,Fan, Xiaohui

, p. 90 - 93 (2014)

Exploration of α,α-dibromo-β-dicarbonyl compounds as novel bromine agents for the conversion of alcohols to alkyl bromides under neutral conditions has been achieved. This method can be used for acid-sensitive substrates and allows the bromination of various primary and secondary alcohols to proceed at room temperature within a very short period of time.

An alternative CuCl-piperidine-catalyzed oxidative homocoupling of terminal alkynes affording 1,3-diynes in air

Zheng, Qingwei,Hua, Ruimao,Wan, Youzhi

, p. 314 - 316 (2010)

CuCl with the use of a catalytic amount of piperidine as additive shows high catalytic activity for the oxidative homocoupling reactions of terminal alkynes in toluene at 60 ?C in air to afford 1,3-diynes in high yields. Copyright
