137302-98-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 137302-98-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,0 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 137302-98:
(8*1)+(7*3)+(6*7)+(5*3)+(4*0)+(3*2)+(2*9)+(1*8)=118
118 % 10 = 8
So 137302-98-8 is a valid CAS Registry Number.

One-pot synthesis of symmetric 1,7-dicarbonyl compounds via a tandem radical addition-elimination-addition reaction

Huang, Zhongyan,Xu, Jiaxi

, p. 15114 - 15120 (2013/09/02)

A novel approach to synthesize symmetric 1,7-dicarbonyl compounds via a tandem radical addition-elimination-addition reaction of S-carbonylmethyl xanthates with allylmethylsulfone and its analogues has been developed. Radicals were produced from S-carbonylmethyl xanthates by adding dilauroyl peroxide and reacted with allylmethylsulfone or analogues to generate terminal olefins as intermediates. The excessive radicals reacted with the intermediate olefins immediately to give adducts of symmetric 1,7-dicarbonyl compounds. This is an efficient method to synthesize 1,7-dicarbonyl compounds under mild conditions. The Royal Society of Chemistry 2013.
