915281-92-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 915281-92-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,5,2,8 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 915281-92:
(8*9)+(7*1)+(6*5)+(5*2)+(4*8)+(3*1)+(2*9)+(1*2)=174
174 % 10 = 4
So 915281-92-4 is a valid CAS Registry Number.

An efficient method for the synthesis of alkylidenecyclobutanones by gold-catalyzed oxidative ring enlargement of vinylidenecyclopropanes

Yuan, Wei,Dong, Xiang,Wei, Yin,Shi, Min

supporting information, p. 10501 - 10505 (2012/11/13)

Rings of gold: Vinylidenecyclopropanes can undergo efficient oxidative ring enlargements under mild conditions to give the corresponding alkylidenecyclobutanone derivatives in good yields (see scheme). A plausible mechanism for this transformation has bee
