Check Digit Verification of cas no
The CAS Registry Mumber 1255188-96-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,5,1,8 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1255188-96:
(9*1)+(8*2)+(7*5)+(6*5)+(5*1)+(4*8)+(3*8)+(2*9)+(1*6)=175
175 % 10 = 5
So 1255188-96-5 is a valid CAS Registry Number.

Enzyme-Catalyzed Asymmetric Domino Thia-Michael/Aldol Condensation Using Pepsin

The novel catalytic promiscuity of pepsin from porcine gastric mucosa for the asymmetric catalysis of the domino thia-Michael/aldol condensation reaction in MeCN and buffer was discovered for the first time. Broad substrate specificity was tested, and a series of corresponding products were obtained with enantioselectivities of up to 84% ee. This specific catalysis was demonstrated by using recombinant pepsin and control experiments with denatured and inhibited pepsin. The reaction was also shown to occur in the active site by site-directed mutagenesis (the Asp32Ala mutant of pepsin), and a possible mechanism was proposed.
