Check Digit Verification of cas no

The CAS Registry Mumber 129731-35-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,7,3 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 129731-35:
(8*1)+(7*2)+(6*9)+(5*7)+(4*3)+(3*1)+(2*3)+(1*5)=137
137 % 10 = 7
So 129731-35-7 is a valid CAS Registry Number.

Dispiro-1,2,4-trioxolanes by Ozonolysis of Cycloalkylidenecycloalkanes on Polyethylene

Griesbaum, Karl,Krieger-Beck, Petra,Beck, Johannes

, p. 391 - 396 (2007/10/02)

Ozonolyses of symmetrical (1b-d) and of unsymmetrical cycloalkylidenecycloalkanes (8a, b) afforded the dispiro-1,2,4-trioxolanes 4b-d and 9a, b, respectively.Their thermal decompositions gave mixtures of the cyclic ketones (3) and lactones (6).Photolysis afforded in addition to 3 and 6 the cyclic anhydrides 13, which are isomeric with the corresponding disoiro-1,2,4-trioxolanes.
