Check Digit Verification of cas no

The CAS Registry Mumber 137272-74-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,7 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 137272-74:
(8*1)+(7*3)+(6*7)+(5*2)+(4*7)+(3*2)+(2*7)+(1*4)=133
133 % 10 = 3
So 137272-74-3 is a valid CAS Registry Number.

Methylamine adenine dinucleotide (MAD): A co-factor to turn alcohol dehydrogenases into aldolases

Wahler, Denis,Reymond, Jean-Louis

, p. 665 - 670 (2007/10/03)

Methylamine adenine dinucleotide (MAD) was prepared in seven steps and 15.3% overall yield from 1-acetoxy-2,3,5-tri-O-benzoyl-D-ribose by chemoenzymatic synthesis. The key step was the phosphate-phosphate coupling between adenosine monophosphate and 2,5-anhydro-1-deoxy-1-phenylacetamide-6-phosphate-D-allitol (3) mediated by carbonyl diimidazole (CDI), followed by the removal of the phenylacetamido group by penicillin G acylase. The MAD co-factor provided a primary amine functionality that was suitably positioned to promote the enamine aldolization of 2-oxopropionamide with aldehydes within the active site of alcohol dehydrogenases, which should lead to the transformation of these stereoselective enzymes into aldolases. Preliminary investigations did not reveal any activity with horse liver alcohol dehydrogenase or yeast alcohol dehydrogenase.
