1219965-71-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1219965-71-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,9,6 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1219965-71:
(9*1)+(8*2)+(7*1)+(6*9)+(5*9)+(4*6)+(3*5)+(2*7)+(1*1)=185
185 % 10 = 5
So 1219965-71-5 is a valid CAS Registry Number.

1, 3-Dipolar cycloaddition reactions of vinylidenecyclopropane-diesters with aromatic diazomethanes generated in situ

Wu, Lei,Shi, Min

, p. 2296 - 2301 (2010)

(Figure Presented) 1, 3-Dipolar cycloaddition reactions of VDCP-diesters with aromatic diazomethanes generated in situ from the corresponding aromatic aldehydes and tosylhydrazine mediated by base produce pyrazole derivatives in good yields under mild conditions. A plausible reaction mechanism has been proposed on the basis of control experiments along with the discussion on the regioselectivity.
