126984-53-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126984-53-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,9,8 and 4 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 126984-53:
(8*1)+(7*2)+(6*6)+(5*9)+(4*8)+(3*4)+(2*5)+(1*3)=160
160 % 10 = 0
So 126984-53-0 is a valid CAS Registry Number.

SILICA GEL-CATALYZED CYCLIZATIONS OF MIXED KETENE ACETALS
Schinzer, Dieter,Kalesse, Markus,Kabbara, Jazid
, p. 5241 - 5244 (2007/10/02)
Mixed ketene acetals of type 2 undergo smooth cyclization upon treatment with silica gel yielding diastereoselectively bicyclooctanones of type 3.Alternatively, the same result was obtained by exposure of the substrates to TiCl4 at low temperature.
