91078-40-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91078-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,7 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 91078-40:
(7*9)+(6*1)+(5*0)+(4*7)+(3*8)+(2*4)+(1*0)=129
129 % 10 = 9
So 91078-40-9 is a valid CAS Registry Number.

PHOTOCHEMICAL REARRANGEMENT OF MORTONIN C
Sanchez, A.,Martinez, M.,Rodriguez-Hahn, L.
, p. 1005 - 1008 (2007/10/02)
Irradiation of Mortonin C (1a) produced the photoproducts 4a and 8a as a result of a photochemically induced ring contraction of the tetrahydro-oxepine nucleus.Te structure and stereochemistry of 4a and 8a were proved by chemical degradation and spectrosc
