Check Digit Verification of cas no

The CAS Registry Mumber 291312-74-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,1,3,1 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 291312-74:
(8*2)+(7*9)+(6*1)+(5*3)+(4*1)+(3*2)+(2*7)+(1*4)=128
128 % 10 = 8
So 291312-74-8 is a valid CAS Registry Number.

TMSCH2Li and TMSCH2Li-LiDMAE: Efficient reagents for noncryogenic halogen-lithium exchange in bromopyridines

Doudouh, Abdelatif,Woltermann, Christopher,Gros, Philippe C.

, p. 4978 - 4980 (2008/02/07)

(Chemical Equation Presented) TMSCH2Li and TMSCH 2Li-LiDMAE have been used efficiently for bromine-lithium exchange in 2-bromo-, 3-bromo-, and 2,5-dibromopyridines under noncryogenic conditions, while low temperatures (-78 to -100°C) are always needed with n-BuLi. The aminoalkoxide LiDMAE induced a remarkable C-2 selectivity with 2,5-dibromopyridines in toluene at 0°C, which was unprecedented at such a temperature. The lithiopyridines were successfully reacted witb electrophiles also under noncryogenic conditions giving the expected adducts in good yields.

, p. 4905 - 4907 (2007/10/03)

(Chemical Equation Presented) The 5-bromopyridyl-2-magnesium chloride (2), which was not accessible previously, was efficiently synthesized for the first time via an iodomagnesium exchange reaction with 5-bromo-2-iodopyridine (1). This reactive intermediate was allowed to react with a variety of electrophiles to afford a range of useful functionalized pyridine derivatives. Application of this methodology to 5-bromo-2-iodo-3-picoline provided a simple and economical synthesis of a key intermediate for the preparation of Lonafarnib, a potent anticancer agent.

Selective monolithiation of 2,5-dibromopyridine with butyllithium
