Check Digit Verification of cas no

The CAS Registry Mumber 1301683-16-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,1,6,8 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1301683-16:
(9*1)+(8*3)+(7*0)+(6*1)+(5*6)+(4*8)+(3*3)+(2*1)+(1*6)=118
118 % 10 = 8
So 1301683-16-8 is a valid CAS Registry Number.

One-pot synthesis of furans using base- and acid-supported reagents Na 2CO3/Al2O3-PPA/SiO2'

Aoyama, Tadashi,Nagaoka, Takashi,Takido, Toshio,Kodomari, Mitsuo

experimental part, p. 619 - 625 (2011/04/15)

A convenient method for the one-pot synthesis of furans from -keto esters and -halo ketones was developed using an acid- and base-supported reagent system Na2CO3/Al2O3-PPA/SiO2'. The condensation reaction of triketones, which are formed from the reaction of -keto esters with -halo ketones in the presence of Na2CO 3/Al2O3, was promoted by PPA/SiO2 to give the corresponding furans in good yields. This method is simple and easy to perform in comparison with stepwise processes, and the yields are good.
