Check Digit Verification of cas no
The CAS Registry Mumber 138507-29-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,0 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138507-29:
(8*1)+(7*3)+(6*8)+(5*5)+(4*0)+(3*7)+(2*2)+(1*9)=136
136 % 10 = 6
So 138507-29-6 is a valid CAS Registry Number.

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 .
