Check Digit Verification of cas no
The CAS Registry Mumber 175276-71-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,2,7 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 175276-71:
(8*1)+(7*7)+(6*5)+(5*2)+(4*7)+(3*6)+(2*7)+(1*1)=158
158 % 10 = 8
So 175276-71-8 is a valid CAS Registry Number.

Ionic liquid as catalyst and reaction medium: A Simple and Efficient Procedure for Paal-Knorr furan synthesis
Wang, Gangqiang,Guan, Zhi,Tang, Rongchang,He, Yanhong
experimental part, p. 370 - 377 (2010/04/04)
The ionic liquid 1-butyl-3-methyl-imidazolium hydrogen sulfate, [bmim]HSO4, efficiently catalyzes Paal-Knorr furan synthesis without any organic solvent. A wide range of aliphatic and aromatic 1,4-diketones easily undergo condensations to form furan derivatives, providing a general and convenient procedure. The Paal-Knorr reaction of ester-substituted 1,4-diketones is first reported. The ionic liquid can be recovered and reused for subsequent runs without any appreciable loss of efficiency.
