Check Digit Verification of cas no

The CAS Registry Mumber 96706-10-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,7,0 and 6 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 96706-10:
(7*9)+(6*6)+(5*7)+(4*0)+(3*6)+(2*1)+(1*0)=154
154 % 10 = 4
So 96706-10-4 is a valid CAS Registry Number.

Synthesis of Polysubstituted Dioxoles from the Cycloaddition of Diazo Dicarbonyl Compounds to Aldehydes and Ketones under Copper(II) Catalysis

Alonso, Miguel E.,Garcia, Maria del Carmen,Chitty, A. Wladimir

, p. 3445 - 3449 (1985)

The copper(II) chelate catalyzed addition of compounds 2-diazo-3-oxobutyrate (3) and 3-diazo-2,4-pentanedione (5) in the presence of aldehydes and ketones in refluxing aromatic solvents proceeds smoothly with the exlusive formation of dioxole derivatives.The yield of 1:1 adducts depends strongly on the nature of the copper ligands and relative concentration of catalyst employed.Dioxoles are the only volatile materials present within a 2percent detection limit. The general character of this novel cycloaddition is illustrated with the reaction of 3 and 5 with four aldehydes and nine ketone substrates.
