78907-82-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78907-82-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,9,0 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 78907-82:
(7*7)+(6*8)+(5*9)+(4*0)+(3*7)+(2*8)+(1*2)=181
181 % 10 = 1
So 78907-82-1 is a valid CAS Registry Number.

Synthesis and Reactions of 3,4-Bis(trimethylsilyl)-1-pyrazolines

Birkofer, Leonhard,Kuehn, Thomas

, p. 2293 - 2299 (2007/10/02)

1,3-Dipolar cycloaddition of diazomethane to the trans-1,2-bis(trimethylsilyl)ethenes 1 a-c affords the trans-3,4-bis(trimethylsilyl)-1-pyrazolines 2 a-c.Thermolysis of 2 a-c yields stereospecifically the trans-1,3-bis(trimethylsilyl)propenes 7 b, c and d.The pyrazoline 2 c is dehalogenated with Zn to give 3(5),4-bis(trimethylsilyl)pyrazole (8).Reaction of 2 a with tetrachloro-o-benzoquinone and of 2 b and c with methanolic NaOH leads to dehydrosilylation and elimination of halogenotrimethylsilane, respectively, with formation of the pyrazoles 9 - 11. 10 and 11 can be desilylated by treatment with acid to yield 12 and 13, resp.
