78128-85-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78128-85-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,1,2 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78128-85:
(7*7)+(6*8)+(5*1)+(4*2)+(3*8)+(2*8)+(1*5)=155
155 % 10 = 5
So 78128-85-5 is a valid CAS Registry Number.

A synthetic route to α-substituted butenolides: Enantioselective synthesis of (+)-ancepsenolide
Ghobril, Cynthia,Kister, Jeremy,Baati, Rachid
, p. 3416 - 3419 (2011/09/13)
A variety of α-substituted butenolides was efficiently synthesized starting from commercially available tetronic acid and carboxylic acids in four steps. The effectiveness of this approach is illustrated in the short synthesis of one of the first butenoli
