Check Digit Verification of cas no

The CAS Registry Mumber 1052074-48-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,2,0,7 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1052074-48:
(9*1)+(8*0)+(7*5)+(6*2)+(5*0)+(4*7)+(3*4)+(2*4)+(1*8)=112
112 % 10 = 2
So 1052074-48-2 is a valid CAS Registry Number.

Stereochemistry and rearrangement reactions of hydroxylignanolactones

Raffaelli, Barbara,Pohjoispaeae, Monika,Hase, Tapio,Cardin, Christine J.,Gan, Yu,Waehaelae, Kristiina

experimental part, p. 2619 - 2627 (2009/02/02)

Various conflicting data on the rearrangement and absolute stereochemistry of hydroxylignano-9,7′-lactones are resolved using 18O labeled compounds, also confirmed by an X-ray analysis of a pure lignano-9,7′- lactone enantiomer, obtained for the first time. Under NaH/DMF rearrangement conditions a silyl protected hydroxylignano-9,9′-lactone underwent an unexpected silyl migration. The Royal Society of Chemistry 2008.
