Check Digit Verification of cas no

The CAS Registry Mumber 1038998-72-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,8,9,9 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1038998-72:
(9*1)+(8*0)+(7*3)+(6*8)+(5*9)+(4*9)+(3*8)+(2*7)+(1*2)=199
199 % 10 = 9
So 1038998-72-9 is a valid CAS Registry Number.

An efficient synthesis of 3-arylmethyl-7,8-dihydro-6H-chromene-2,5-diones from Baylis-Hillman adduct acetates under solvent-free conditions

Zhong, Weihui,Zhao, Yongzhi,Su, Weike

, p. 5491 - 5496 (2008/12/20)

A simple, efficient synthesis of 3-arylmethyl-7,8-dihydro-6H-chromene-2,5-dione 4 from Baylis-Hillman adduct acetates derived from aromatic aldehydes and cyclohexane-1,3-diones under solvent-free conditions is described. Interestingly, when Baylis-Hillman adducts derived from aliphatic aldehydes were tested under the similar conditions, the unexpected stereoisomers 5 and 6 were obtained in moderate yields. A plausible mechanism for the formation of 4-6 is proposed.
