Check Digit Verification of cas no

The CAS Registry Mumber 77940-55-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,4 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77940-55:
(7*7)+(6*7)+(5*9)+(4*4)+(3*0)+(2*5)+(1*5)=167
167 % 10 = 7
So 77940-55-7 is a valid CAS Registry Number.

Substituent effects in [2σ + 2σ + 2σ] thermal decarbonylation of cage ketones. Remarkably effective elongation of strained C-C bond by through-bond coupling

Harano, Kazunobu,Ban, Takashi,Yasuda, Masami,Osawa, Eiji,Kanematsu, Ken

, p. 2310 - 2317 (2007/10/21)

Strained pentacyclic ketones (5a-d) were prepared in high yields by photoinduced [4 + 2]π cycloadduct of N-(ethoxycarbonyl)azepine with substituted cyclopentadienones. The structure of one of the cage ketones (5d) was confirmed by X-ray analysis to be 1,2
