891192-05-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 891192-05-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,1,1,9 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 891192-05:
(8*8)+(7*9)+(6*1)+(5*1)+(4*9)+(3*2)+(2*0)+(1*5)=185
185 % 10 = 5
So 891192-05-5 is a valid CAS Registry Number.

DBU catalyzed cyanoacylation of ketones with acyl cyanides
Zhang, Wen,Shi, Min
, p. 1671 - 1674 (2006)
The reaction of cyclohexanone with benzoyl cyanide by amines provides the corresponding O-benzoyl cyanohedrin adducts in moderate to good yields under mild conditions. DBU was found to be the most effective promoter among the catalyst, allowing the reacti
