Check Digit Verification of cas no

The CAS Registry Mumber 1258212-71-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,2,1 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1258212-71:
(9*1)+(8*2)+(7*5)+(6*8)+(5*2)+(4*1)+(3*2)+(2*7)+(1*1)=143
143 % 10 = 3
So 1258212-71-3 is a valid CAS Registry Number.

Mild and efficient synthesis of benzimidazole using lead peroxide under solvent-free conditions

Patil, Vishvanath D.,Patil, Jaymala,Rege, Priyanka,Dere, Ganesh

, p. 58 - 62 (2011)

Benzimidazole derivatives have been synthesized using a catalytic amount of lead peroxide (PbO2) at room temperature with excellent yields. The remarkable selectivities under mild, neutral and solvent-free conditions and use of a commercially available, inexpensive catalyst are attractive features of this method. Copyright

Novel method for the syntheses of 2-substituted benzimidazoles using Ti(IV) isopropoxide and cumene hydroperoxide
