80945-34-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 80945-34-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,9,4 and 5 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 80945-34:
(7*8)+(6*0)+(5*9)+(4*4)+(3*5)+(2*3)+(1*4)=142
142 % 10 = 2
So 80945-34-2 is a valid CAS Registry Number.

RING OPENING OF CYCLOPROPYL KETONES ASSISTED BY THE TRIMETHYLSILYL GROUP

Ochiai, Masahito,Sumi, Kenzo,Fujita, Eiichi

, p. 79 - 80 (1982)

Cyclopropyl ketones 2 were smoothly cleaved with boron trifluoride-acetic acid under mild reaction conditions by the assistance of trimethylsilyl group to give γ,δ-enones in good yields and the reaction was applied to the formal total synthesis of cis-jasmone.

Silicon-Assisted Ring Opening of Cyclopropyl Ketones with Boron Trifluoride-Acetic Acid Complex

Ochiai, Masahito,Sumi, Kenzo,Fujita, Eiichi

, p. 3931 - 3938 (2007/10/02)

2-(Trimethylsilylmethyl)cyclopropyl ketones were smoothly cleaved with boron trifluoride-acetic acid complex under mild reaction conditions with the assistance of the trimethylsilyl group to give γ,δ-enones in good yields.The major effect of the trimethylsilyl group in the ring opening of the cyclopropyl ketones was unambiguously confirmed in the dicyclopropyl ketone 15: one of its two cyclopropyl rings, which has a trimethylsilylmethyl group, was selectively cleaved.Furthermore, the reaction was applied to the formal total synthesis of cis-jasmone.Keywords - ring opening of cyclopropyl ketone; trimethylsilyl group; γ,δ-enone; cis-jasmone; allylsilane; boron trifluoride-acetic acid
