94697-73-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94697-73-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,6,9 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 94697-73:
(7*9)+(6*4)+(5*6)+(4*9)+(3*7)+(2*7)+(1*3)=191
191 % 10 = 1
So 94697-73-1 is a valid CAS Registry Number.

Diastereoselective Aldol Reactions of β-Silylenolates: A Formal Synthesis of Thienamicin
Fleming, Ian,Kilburn, Jeremy D.
, p. 1198 - 1199 (1986)
The lithium enolate (1) of benzyl β-phenyldimethylsilylbutanoate reacts with β-phenyldimethylsilylpropionaldehyde (2) to give, with high diastereoselectivity, the aldol product (3), which is converted into the β-lactam (7), a known precursor of thienamyci
