120696-17-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120696-17-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,6,9 and 6 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 120696-17:
(8*1)+(7*2)+(6*0)+(5*6)+(4*9)+(3*6)+(2*1)+(1*7)=115
115 % 10 = 5
So 120696-17-5 is a valid CAS Registry Number.

DRASTIC CONVERSION OF BICYCLO(m,n,O)ALKANE RINGS TO SPIROCYCLIC SKELETONS
Nagumo, Shinji,Suemune, Hiroshi,Sakai, Kiyoshi
, p. 6927 - 6930 (2007/10/02)
Under acetalization conditions (BF3/ethylene glycol), bicyclo(m.n.O)alkanones with the carbonyl function at 3' or 4'-position of the C1-side chain undergo the ring cleavage to build up the spirocyclic skeletons.
