51951-47-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 51951-47-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,9,5 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 51951-47:
(7*5)+(6*1)+(5*9)+(4*5)+(3*1)+(2*4)+(1*7)=124
124 % 10 = 4
So 51951-47-4 is a valid CAS Registry Number.

A versatile and highly efficient method for 1-chlorination of terminal and trialkylsilyl-protected alkynes

Gulia, Nurbey,Pigulski, Bartlomiej,Charewicz, Marta,Szafert, Slawomir

supporting information, p. 2746 - 2749 (2014/03/21)

A highly efficient one-pot procedure for the preparation of 1-chloroalkynes and 1-chlorobutadiynes from terminal and trialkylsilyl-protected precursors is reported. This convenient reaction, proceeding under mild conditions, utilizes N-chlorosuccinimide as the chlorinating agent and tolerates a range of functional groups. A general chlorination of alkynes: A highly efficient one-pot procedure for the preparation of 1-chloroalkynes and 1-chlorobutadiynes from terminal and trialkylsilyl-protected precursors is reported (see figure; TMS=trimethylsilyl, TES=triethylsilyl, TBDMS=tert-butyldimethylsilyl, TIPS=triisopropylsilyl). This convenient reaction, proceeding under mild conditions, utilizes N-chlorosuccinimide as the chlorinating agent and tolerates a range of functional groups.
