Check Digit Verification of cas no

The CAS Registry Mumber 16250-89-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,2,5 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 16250-89:
(7*1)+(6*6)+(5*2)+(4*5)+(3*0)+(2*8)+(1*9)=98
98 % 10 = 8
So 16250-89-8 is a valid CAS Registry Number.

The synthesis of new 1,3-oxazolidines and 1,3-oxazinanes containing (η6-arene)tricarbonylchromium group based on condensation between aldehydes and amino alcohols

Artemov,Sazonova,Krylova,Zvereva,Pechen,Fukin,Cherkasov,Faerman,Grishina, N. Yu.

, p. 884 - 892 (2018/08/28)

The condensation reactions of β- and γ-amino alcohols containing phenyl or (η6-arene) tricarbonylchromium substituent with formaldehyde, acetaldehyde, benzaldehyde, and (η6-benzaldehyde)tricarbonylchromium were studied. The resulting 1,3-oxazolidine and 1,3-oxazinane products were isolated in a pure form and identified by different physicochemical methods. The effect of (η6-arene)tricarbonylchromium moiety on the reaction process was demonstrated.

OXAZOLIDINES. 2. SYNTHESIS OF 2-METHYLOXAZOLIDINES BY CYCLIZATION OF VINYL ETHERS OF 1,2-AMINO ALCOHOLS

Kukharev, B.F.,Stankevich, V.K.,Klimenko, G.R.,Terent'eva, V.P.,Kukhareva, V.A.

, p. 440 - 442 (2007/10/02)

A study has been made of the catalytic activity of a number of proton acids and Lewis acids, amongst which mercury salts were particularly active, in the cyclization of N-phenylethanolamine vinyl ether to 2-methyl-3-phenyloxazolidine.A method for the preparative synthesis of 2-methyloxazolidines has been developed.
