117775-73-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117775-73-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,7,7 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 117775-73:
(8*1)+(7*1)+(6*7)+(5*7)+(4*7)+(3*5)+(2*7)+(1*3)=152
152 % 10 = 2
So 117775-73-2 is a valid CAS Registry Number.

Amino Acid Esters as Chiral Auxiliaries in Lewis Acid Catalyzed Diels-Alder Reactions
Waldmann, Herbert
, p. 671 - 680 (2007/10/02)
Cylopentadiene, cyclohexadiene and alkyl-substituted butadienes react with N-acryloyl-, N-crotonoyl- and N-(4-nitrocinnamoyl)-(S)-proline benzyl and allyl ester in the presence of Lewis acids to give the cycloadducts in high yields and with stereoselectiv
