Check Digit Verification of cas no

The CAS Registry Mumber 211187-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,1,8 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 211187-99:
(8*2)+(7*1)+(6*1)+(5*1)+(4*8)+(3*7)+(2*9)+(1*9)=114
114 % 10 = 4
So 211187-99-4 is a valid CAS Registry Number.

Generation of Radical Species from Cyclohexane-1,2-dione and the Reaction with Olefins: Preparation of 4,5-Dihydro-7(6H)-benzofuranone Derivatives

Miura, Masanori,Arai, Noriyoshi,Narasaka, Koichi

, p. 1437 - 1441 (1998)

Oxidation of cyclohexane-1,2-dione with ammonium hexanitratocerate(IV) (CAN) generates 2,3-dioxocyclohexyl radical, which reacts with electron-rich olefins to afford the corresponding addition products. The adducts thus generated are converted to 4,5-dihydro-7(6H)-benzofuranone by acid treatment. In addition to cyclohexane-1,2-dione, radical species are also generated from cyclopentane-1,2-dione and cycloheptane-1,2-dione.
