Check Digit Verification of cas no

The CAS Registry Mumber 552855-95-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,2,8,5 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 552855-95:
(8*5)+(7*5)+(6*2)+(5*8)+(4*5)+(3*5)+(2*9)+(1*5)=185
185 % 10 = 5
So 552855-95-5 is a valid CAS Registry Number.

Efficient synthesis of 3-Aminoimidazo[1,2-a] pyridines using silica-supported perchloric acid (HClO4-SiO2) as a novel heterogenous catalyst

Habibi, Azizollah,Tarameshloo, Zahra,Rostamizadeh, Shahnaz,Amani, Ali M.

, p. 155 - 159 (2012)

One pot three-component reaction of 2-amino pyridines, aldehydes and isocyanides in the presence of silicasupported perchloric acid (HClO 4-SiO2), produces 3-aminoimidazo[1,2-a] pyridines in excellent yields. The reaction time is sho

An efficient, regioselective, versatile synthesis of N-fused 2- and 3-aminoimidazoles via Ugi-type multicomponent reaction mediated by zirconium(IV) chloride in polyethylene glycol-400

Guchhait, Sankar K.,Madaan, Chetna

scheme or table, p. 628 - 632 (2009/07/01)

An Ugi-type multicomponent reaction of heterocyclic amidines with aldehydes and isocyanides catalyzed by zirconium(IV) chloride in PEG-400 was developed. The protocol offers the rapid, environment friendly, regioselective and versatile synthesis of medici
