126495-04-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 126495-04-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,4,9 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 126495-04:
(8*1)+(7*2)+(6*6)+(5*4)+(4*9)+(3*5)+(2*0)+(1*4)=133
133 % 10 = 3
So 126495-04-3 is a valid CAS Registry Number.

A PRACTICAL PROCEDURE FOR THE CONVERSION OF ALDEHYDES TO TERMINAL ALKYNES BY A ONE CARBON HOMOLOGATION

Hijfte, Luc Van,Kolb, Michael,Witz, Pascale

, p. 3655 - 3656 (1989)

A convenient method for the conversion of aldehydes to terminal alkynes via the corresponding 1,1-dibromoalkenes is described.The key feature of the process is the use of megnesium in tetrahydrofuran for the debromination step.
