Check Digit Verification of cas no
The CAS Registry Mumber 4180-13-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,8 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4180-13:
(6*4)+(5*1)+(4*8)+(3*0)+(2*1)+(1*3)=66
66 % 10 = 6
So 4180-13-6 is a valid CAS Registry Number.

Decarbonylation of Tetrahydrofuran-2-carboxylic Acids and Tetrahydropyrane-2-carboxylic Acids in Concentrated Sulfuric acid: Formation of Oxonium Ions
Bates, Hans Aaron
, p. 2490 - 2493 (2007/10/02)
Tetrahydrofuran-2-carboxylic acids 1, 3, and 5 readily decarbonylate in 96percent sulfuric acid, generating stable oxonium ions 2, 4, and 6, respectively.Analogously, tetrahydropyran-2-carboxylic acids 7, 9, 12, and 14a produce oxonium ions 8, 10, 13, and 15, respectively.These oxonium ions are quite stable, with the exception of 10, which partially isomerizes to 11, and 13, which rearranges to ions 17 and 21.Details in the transformation of oxonium ion 15 into lactone 23 by way of open chain acid 22a were elucidated.
