Check Digit Verification of cas no

The CAS Registry Mumber 130042-99-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,0,4 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 130042-99:
(8*1)+(7*3)+(6*0)+(5*0)+(4*4)+(3*2)+(2*9)+(1*9)=78
78 % 10 = 8
So 130042-99-8 is a valid CAS Registry Number.

Selective Cβ-O Bond Cleavage of Chalcone Epoxides Induced by Pyrylium Salt Sensitized Photoreactions and Dark Reactions with Cerium(IV) Salts

Hasegawa, Eietsu,Ishiyama, Kenyuki,Kashiwazaki, Hiroki,Horaguchi, Takaaki,Shimizu, Takahachi

, p. 4045 - 4048 (1990)

The Cβ-O bonds of chalcone epoxides (1a, 1b) were selectively cleaved by pyrylium salt sensitized photoreactions, affording β-ketoaldehydes (2a, 2b) in CH2Cl2 and MeOH-adducts (3a, 3b) in MeOH.Similarly, cerium(IV) salts catalyzed the MeOH-adduct formations of 1a and 1b in the dark.On the other hand, nitrate ester (4b) was obtained on treatment of 1b with a cerium(IV) salt in MeCN.
