Check Digit Verification of cas no

The CAS Registry Mumber 908023-69-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,8,0,2 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 908023-69:
(8*9)+(7*0)+(6*8)+(5*0)+(4*2)+(3*3)+(2*6)+(1*9)=158
158 % 10 = 8
So 908023-69-8 is a valid CAS Registry Number.

Synthesis of secondary amines by titanium-mediated transfer of alkenyl groups from alcohols

Ramanathan, Balasubramanian,Odom, Aaron L.

, p. 9344 - 9345 (2007/10/03)

Reaction of Ti(NMe2)4 with allyl alcohols and primary amines leads to the selective formation of secondary allylic amines. The allyl transfer from the alcohol to the amine occurs with selective allylic transposition. Due to substituent effects in the reactions, we postulate that the reaction occurs through a [2 + 2]/retro-[2 + 2]-cycloaddition mechanism. It was also found that a similar reaction could be accomplished with homoallylic alcohol. In this case, the more complex mechanism leads to the formation of 1-aza-spiro[5.5]undecane. Possible pathways for the homoallylic transfer and cyclization are discussed. Copyright
