16526-68-4 Usage
Purification Methods
Purify it also by conversion to the triethyl ester b 217-218o/10mm, 151o/1mm, the distillate solidifies on cooling, m 36-37o, which is hydrolysed by boiling in aqueous HCl. The trimethyl ester can be distilled and recrystallised from Et2O, m 48-49o. [Newman & Lawrie J Am Chem Soc 76 4598 1954, Lukes &S Galik Coll Czech Chem Comm 19 712 1954, Beilstein 9 III 4749.]
Check Digit Verification of cas no
The CAS Registry Mumber 16526-68-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,5,2 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 16526-68:
(7*1)+(6*6)+(5*5)+(4*2)+(3*6)+(2*6)+(1*8)=114
114 % 10 = 4
So 16526-68-4 is a valid CAS Registry Number.

3,5,7-Trimethyl-1-azatricyclo[3.3.1.13,7]decan-2-ylidene, an aminocarbene without π conjugation, has been generated from the corresponding tosylhydrazone salt. Addition of the carbene to alkenes is stereospecifically cis, thus showing that the
