103344-56-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103344-56-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,3,4 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 103344-56:
(8*1)+(7*0)+(6*3)+(5*3)+(4*4)+(3*4)+(2*5)+(1*6)=85
85 % 10 = 5
So 103344-56-5 is a valid CAS Registry Number.

Isomerization of alkyl branched alkynoic acids
Abrams, Suzanne R.
, p. 457 - 463 (2007/10/02)
Acetylenic acids are isomerized by alkali metal amides of 1,3-diaminopropene to 3,5-dienoic acids.An acid with a methyl branch at C-3 separating the carboxyl from the triple bond is rearranged to a mixture of the terminal alkynoic acid and two isomeric 3,
