4409-99-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4409-99-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,0 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4409-99:
(6*4)+(5*4)+(4*0)+(3*9)+(2*9)+(1*9)=98
98 % 10 = 8
So 4409-99-8 is a valid CAS Registry Number.

HYDRATION TRIMERIZATION OF ACETYLENE IN SUPERBASIC MEDIA III. VINYLATION OF ACETYLENIC ALCOHOLS AS INTERMEDIATE STAGE

Tarasova, O. A.,Trofimov, B. A.,Afonin, A. V.,Sinegovskaya, L. M.,Kalinina, N. A.,Amosova, S. V.

, p. 1018 - 1025 (2007/10/02)

It was confirmed that the hydration-trimerization of acetylene to 2-vinyloxy-1,3-butadiene in superbasic media takes place by a stepwise mechanism, involving the initial formation of acetaldehyde, its ethynylation, vinylation of the acetylenic alcohol, and prototropic acetyl-allene-1,3-diene rearrangements.A method was developed for the direct vinylation of primary and secondary acetylenic alcohols in the potassium hydroxide-DMSO system, leading to 3-vinyloxy-1-alkynes and 3-vinyloxy-1,2-alkadienes with overall yields of 45-87percent .
