Check Digit Verification of cas no

The CAS Registry Mumber 77128-29-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,2 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 77128-29:
(7*7)+(6*7)+(5*1)+(4*2)+(3*8)+(2*2)+(1*9)=141
141 % 10 = 1
So 77128-29-1 is a valid CAS Registry Number.

PHOTOCYCLIZATION OF BENZOFURANCARBOXANILIDES. PHOTOREARRANGEMENT OF THE BENZODIHYDROFURAN SYSTEM TO 3-o-HYDROXYPHENYLQUINOLONES

Kanaoka, Yuichi,San-nohe, Kunio

, p. 3893 - 3896 (2007/10/02)

cis-Dihydrobenzofuroquinolone (4a) and cis-dihydrobenzofuroquinolone (5) undergo photorearrangement, characteristic to the benzodihydrofuran system, leading to 3-o-hydroxyphenylquinolone (6).A plausible mechanism involving a cyclopropyl dienone (12) was discussed.
