Check Digit Verification of cas no

The CAS Registry Mumber 122476-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,4,7 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 122476-83:
(8*1)+(7*2)+(6*2)+(5*4)+(4*7)+(3*6)+(2*8)+(1*3)=119
119 % 10 = 9
So 122476-83-9 is a valid CAS Registry Number.

Syntheses of 5-Alkenylpyrimidines by Organotin Reactions

Sandosham, Jessie,Benneche, Tore,Moeller, Bjoerg,Undheim, Kjell

, p. 455 - 461 (2007/10/02)

5-Stannylpyrimidines can be prepared from the corresponding bromides by lithiation at -95 deg C and quenching with tributylstannyl chloride.The 5-stannyl-pyrimidine is used in Pd-catalyzed coupling reactions with vinyl bromides.The opposite reaction sequence, i.e.Pd-catalyzed coupling between 5-halopyrimidines and vinyltin derivatives, is also described.Alternatively, the 5-vinylpyrimidines have been obtained by dehydrohalogenation with cesium fluoride and by a modified Wittig reaction. 2-Methylthiopyrimidines are transformed into the 2-methoxy derivatives or 2-pyrimidinones using chloramine-T (CAT) in a simple one-pot synthesis.
