Check Digit Verification of cas no

The CAS Registry Mumber 112473-08-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,4,7 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 112473-08:
(8*1)+(7*1)+(6*2)+(5*4)+(4*7)+(3*3)+(2*0)+(1*8)=92
92 % 10 = 2
So 112473-08-2 is a valid CAS Registry Number.

A New Entry to 1,2,4-Benzenetriol Congeners

Ozaki, Yutaka,Kim, Sang-Won

, p. 1199 - 1200 (1987)

1,2,4-Benzenetriol derivatives were efficiently prepared from annulation of α,α-bis(ethylthio)carbonyl compounds with α,β-unsaturated carbonyl compounds.

A NEW SYNTHESIS OF 1,2,4-BENZENETRIOL CONGENERS

Ozaki, Yutaka,Kim, Sang-Won

, p. 304 - 307 (2007/10/02)

1,2,4-Benzenetriols were synthesized via 4,4-bis(ethylthio)-1,3-cyclohexanediones which were prepared by means of two types of Michael-Claisen condensation starting from methyl bis(ethylthio)acetate or 1,1-bis(ethylthio)-2-propanone.Keywords- annelation; aromatic synthesis; 1,2,4-benzenetriol; methyl bis(ethylthio)acetate; 1,1-bis(ethylthio)-2-propanone; C2+C4 annelation; C3+C3 annelation; Michael-Claisen condensation; α,β-unsaturated ester; dibenzofurandiol
