Check Digit Verification of cas no

The CAS Registry Mumber 1400998-54-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,0,9,9 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1400998-54:
(9*1)+(8*4)+(7*0)+(6*0)+(5*9)+(4*9)+(3*8)+(2*5)+(1*4)=160
160 % 10 = 0
So 1400998-54-0 is a valid CAS Registry Number.

4-Isocyanopermethylbutane-1,1,3-triol (IPB): A convertible isonitrile for multicomponent reactions

Neves Filho, Ricardo A.W.,Stark, Sebastian,Morejon, Micjel C.,Westermann, Bernhard,Wessjohann, Ludger A.

, p. 5360 - 5363 (2012/10/30)

The synthesis and applications of 4-isocyanopermethylbutane-1,1,3-triol (IPB) as a new convertible isonitrile (isocyanide) for isocyanide-based multicomponent reactions (IMCRs) like Ugi, Ugi-Smiles, and Passerini reactions are described. The primary products obtained from these IMCRs can be converted into highly activated N-acylpyrroles, which upon treatment with nucleophiles can be transformed into carboxylic acids, esters, amides, alcohols, and olefins. In this sense the reagent can be seen as a neutral carbanion equivalent to formate (HO2C-), and carboxylates or carboxamides etc. (RNu-CO-).
