219982-05-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219982-05-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,9,8 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 219982-05:
(8*2)+(7*1)+(6*9)+(5*9)+(4*8)+(3*2)+(2*0)+(1*5)=165
165 % 10 = 5
So 219982-05-5 is a valid CAS Registry Number.

Reaction of 2-nitrobenzaldehyde with vinyl carbonyl compounds in the presence of 1,4-diazabicyclo[2.2.2]octane affords Baylis-Hillman products, catalytic reduction of which results in direct cyclisation to quinoline derivatives.
