77504-14-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77504-14-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,0 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77504-14:
(7*7)+(6*7)+(5*5)+(4*0)+(3*4)+(2*1)+(1*4)=134
134 % 10 = 4
So 77504-14-4 is a valid CAS Registry Number.

Clay Montmorillonite-Catalyzed Aldol Reactions of Silyl Enol Ethers with Aldehydes and Acetals
Kawai, Motomitsu,Onaka, Makoto,Izumi, Yusuke
, p. 1581 - 1584 (2007/10/02)
By the use of clay montmorillonite as a catalyst, cross aldol adducts are obtained from silyl enol ethers and aldehydes or acetals.The diastereoselectivity in the reaction is significantly sensitive to the solvent used.
