Check Digit Verification of cas no

The CAS Registry Mumber 78992-73-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,9,9 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 78992-73:
(7*7)+(6*8)+(5*9)+(4*9)+(3*2)+(2*7)+(1*3)=201
201 % 10 = 1
So 78992-73-1 is a valid CAS Registry Number.

A one-pot synthesis of 3-arylglutaric anhydrides by reaction of ketene with aromatic aldehydes and ketones

Matsunaga, Hirokazu,Ikeda, Kiyoshi,Iwamoto, Ken-ichi,Suzuki, Yumiko,Sato, Masayuki

experimental part, p. 2334 - 2336 (2009/09/06)

Aromatic aldehydes and ketones react with ketene under Lewis acid catalysis to produce β-lactones, which in situ react with another molecule of ketene to produce 3-arylglutaric anhydrides. The mechanism, scope, and limitation of this one-pot synthesis of 3-substituted glutaric anhydrides are discussed.
