75332-10-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75332-10-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,3,3 and 2 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75332-10:
(7*7)+(6*5)+(5*3)+(4*3)+(3*2)+(2*1)+(1*0)=114
114 % 10 = 4
So 75332-10-4 is a valid CAS Registry Number.

Addition of n-Butyllithium to Hydroxybicyclohept-2-enes

Richey, Herman G.,Wilkins, Cletus W.,Bension, Rouvain M.

, p. 5042 - 5047 (1980)

n-Butyllithium adds to the double bonds of bicyclohept-2-ene (7), endo-bicyclohept-5-en-2-ol (9), exo-bicyclohept-5-en-2-ol (12), syn-bicyclohept-2-en-7-ol (14), and anti-bicyclohept-2-en-7-ol (18).The n-butyl group was shown to be attached at an exo position and in the additions to 9 and 12 to be at C-5 rather than C-6.Competition experiments suggest that addition to 9 is somewhat faster than to 7 but that additions to 14 and 18 are slower.The role of a metalated hydroxyl group in assisting these reactions is considered.No addition products were obtained from reactions at ambient temperature of n-butyllithium with 3-(hydroxymethyl)-1,2-diethylcyclopropene (20), 3-(hydroxymethyl)-1,2-dimethylcyclopropene (23), or 3-(hydroxymethyl)-1-propylcyclopropene (24), but some 1-(hydroxymethyl)-2-ethylidene-3-deuterio-3-ethylcyclopropane (21) was obtained from a reaction with 20 at dry ice temperature followed by quenching with D2O.
