Check Digit Verification of cas no

The CAS Registry Mumber 29443-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,4,4 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 29443-50:
(7*2)+(6*9)+(5*4)+(4*4)+(3*3)+(2*5)+(1*0)=123
123 % 10 = 3
So 29443-50-3 is a valid CAS Registry Number.

Studies on the Synthesis of Heterocyclic Compounds. XVI. Cleavage of 1,3-Benzodioxoles and -Benzoxathioles by Sodium Iodide-Acyl Chloride

Corda, Luciana,Fadda, Anna Maria,Maccioni, Antonio,Maccioni, Anna Maria,Podda, Gianni

, p. 311 - 314 (2007/10/02)

The cleavage reaction of ethereal and thioethereal bonds with sodium iodide and acyl chloride has been studied.In all the 1,3-benzodioxoles and -benzoxathioles studied, the opening of the heterocyclic ring with formation of 1,2-diacetoxybenzene or 2-hydroxythiophenol diacetic acid ester and gem-diiodoalkanes and iodoalkenes has been observed.The structure of newly prepared compounds has been determined by analytical and spectroscopic data or comparison with authentic samples.
