Check Digit Verification of cas no
The CAS Registry Mumber 18956-18-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,5 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 18956-18:
(7*1)+(6*8)+(5*9)+(4*5)+(3*6)+(2*1)+(1*8)=148
148 % 10 = 8
So 18956-18-8 is a valid CAS Registry Number.

A new domino oxidation—rearrangement of 2,3-dihydrowogonin to negletein
Spoerlein-Guettler, Cornelia,Milius, Wolfgang,Obenauf, Johannes,Schobert, Rainer
, p. 1560 - 1562 (2018/03/29)
We report an expeditious, iodine-catalysed oxidation of 2,3-dihydrowogonin to negletein which comprises a Wessely–Moser rearrangement (WMR), associated not with an O-demethylation, as usual, but with an oxygen to oxygen methyl shift. In contrast, DDQ in 1
