Check Digit Verification of cas no

The CAS Registry Mumber 1442748-91-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,2,7,4 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1442748-91:
(9*1)+(8*4)+(7*4)+(6*2)+(5*7)+(4*4)+(3*8)+(2*9)+(1*1)=175
175 % 10 = 5
So 1442748-91-5 is a valid CAS Registry Number.

Direct Aerobic Oxidative Reactions of 2-Hydroxyacetophenones

Sahoo, Subas Chandra,Nath, Utpal,Pan, Subhas Chandra

supporting information, p. 4434 - 4438 (2017/08/23)

Valuable and direct aerobic oxidation reactions of 2-hydroxyacetophenones were explored. The concept was based on the in situ treatment of small quantities of aerobically formed α-keto aldehydes that drove the reactions to the corresponding products. This new strategy was applied for a variety of oxidative reactions of 2-hydroxyacetophenones, and valuable products such as phthalides, quinoxalines, and α-keto amides were obtained in good to high yields.
