127896-12-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127896-12-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,8,9 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 127896-12:
(8*1)+(7*2)+(6*7)+(5*8)+(4*9)+(3*6)+(2*1)+(1*2)=162
162 % 10 = 2
So 127896-12-2 is a valid CAS Registry Number.

A MILD FOUR-CARBON HOMOLOGATION OF ALDEHYDES TO E,E-DIENAMINES
Kende, Andrew S.,DeVita, Robert J.
, p. 307 - 310 (2007/10/02)
The four-carbon homologation of aldehydes to E,E-dienamines can be achieved efficiently under mild conditions by iodomethylenation with CrCl2-CHI3, with subsequent Pd-catalyzed coupling to the vinylstannane 4 followed by mild cleavage of the FMOC group.
