Check Digit Verification of cas no

The CAS Registry Mumber 135305-70-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,3,0 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 135305-70:
(8*1)+(7*3)+(6*5)+(5*3)+(4*0)+(3*5)+(2*7)+(1*0)=103
103 % 10 = 3
So 135305-70-3 is a valid CAS Registry Number.

The Photosensitized Oxygenation of Furanoeremophilanes. III. The Transformations to the Skeletally Isomeric Lactones from Furanofukinol

Naya, Keizo,Shimizu, Mitsuaki,Nishio, Hideki,Takeda, Motonori,Oka, Shogo,Hirota, Keiji

, p. 1071 - 1080 (1991)

Pairs of the skeletal isomers of eremophilane-type lactones were synthesized from furanofukinol via photosensitized oxygenation, followed by lactone cleavage and refomation.Their stereochemistry has been clarified so as to be consistent with a classification method outlined in our earlier papers.
