Check Digit Verification of cas no

The CAS Registry Mumber 222308-12-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,2,3,0 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 222308-12:
(8*2)+(7*2)+(6*2)+(5*3)+(4*0)+(3*8)+(2*1)+(1*2)=85
85 % 10 = 5
So 222308-12-5 is a valid CAS Registry Number.

Concave reagents, 28. - Comparison of bimacrocyclic, monomacrocyclic, and nonmacrocyclic bis(amidomethyl)pyridines as catalysts in the base- catalyzed addition of alcohols to ketenes

Petersen, Soenke,Luening, Ulrich

, p. 847 - 854 (1999)

Nineteen new bimacrocyclic, monomacrocyclic, and nonmacrocyclic pyridines 1-6 bearing amide functions have been synthesized and utilized in base-catalyzed additions of alcohols (ethanol, 2-propanol) and polyols [propane-1,2-diol (11a), butane-1,3-diol (12a), methyl 4,6-O-benzylidene-α- D-glucopyranoside (13a)] to diphenylketene. Compounds 4c, 4d and 1b proved to be efficient and selective catalysts; 4c and 4d exhibited better results with 11a and 12a, and 1b was the best catalyst for selective 2-O-acylation of 13a.
