Check Digit Verification of cas no

The CAS Registry Mumber 300710-85-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,0,7,1 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 300710-85:
(8*3)+(7*0)+(6*0)+(5*7)+(4*1)+(3*0)+(2*8)+(1*5)=84
84 % 10 = 4
So 300710-85-4 is a valid CAS Registry Number.

Synthesis of 1,2,4-ditellurazolidines by oxidative ring contraction of 2H,6H-tetrahydro-1,5,3,7-ditelluradiazocines

, p. 870 - 871 (2000)

Synthesis of novel five-membered cyclic ditellurides, 4-aryl-1,2,4-ditellurazolidines was achieved by treating 3,7-diaryl-2H,6H-tetrahydro-1,5,3,7-ditelluradiazocines with oxidizing agents or by aerobic exposure. The oxidative ring contraction of the heterocycles was assumed to proceed through formation and subsequent fragmentation of bicyclic ditellura dications.

Synthesis and oxidative ring contraction of 1,5,3,7-dichalcogenadiazocanes. Novel formation of 1,2,4-diselenazolidines, 1,2,4-ditellurazolidines, and 1,2,3,4,5,7-pentathiazocanes

1,5,3,7-Dithiadiazocanes, 1,5,3,7-diselenadiazocanes, and 1,5,3,7-ditelluradiazocanes were prepared from a primary amine, formalin, and H2S, NaSeH, or NaTeH, respectively. Oxidation of 1,5,3,7- diselenadiazocanes and 1,5,3,7-ditelluradiazocanes using NBS efficiently afforded 1,2,4-diselenazolidines or 1,2,4-ditellurazolidines, respectively. In contrast, treatment of 1,5,3,7-dithiadiazocanes with bromine-elemental sulfur or disulfur dichloride (S2Cl2) afforded 1,2,3,4,5,7- pentathiazocanes. An unusual oxidative conversion of 1,5,3,7- dichalcogenadiazocanes into these products was assumed to proceed through in situ formation of 1,5,3,7-dichalcogenadiazabicyclo[3.3.0]octane-type dications.
