Check Digit Verification of cas no

The CAS Registry Mumber 272130-53-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,2,1,3 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 272130-53:
(8*2)+(7*7)+(6*2)+(5*1)+(4*3)+(3*0)+(2*5)+(1*3)=107
107 % 10 = 7
So 272130-53-7 is a valid CAS Registry Number.

AMP deaminase inhibitors. 3. SAR of 3-(carboxyarylalkyl)coformycin aglycon analogues

Kasibhatla, Srinivas Rao,Bookser, Brett C.,Probst, Gary,Appleman, James R.,Erion, Mark D.

, p. 1508 - 1518 (2007/10/03)

N3-Substituted coformycin aglycon analogues with improved AMP deaminase (AMPDA) inhibitory potency are described. Replacement of the 5-carboxypentyl substituent in the lead AMPDA inhibitor 3-(5-carboxypentyl)-3,6,7,8- tetrahydroimidazo[4,5-d][1,3]diazepin-8-ol (2) described in the previous article with various carboxyarylalkyl groups resulted in compounds with 10- 100-fold improved AMPDA inhibitory potencies. The optimal N3 substituent had m-carboxyphenyl with a two-carbon alkyl tether. For example, 3-[2-(3-carboxy- 5-ethylphenyl)ethyl]-3,6,7,8-tetrahydroimidazo[4,5-d][1,3]diazepin-8-ol (43g) inhibited human AMPDA with a K(i) = 0.06 μM. The compounds within the series also exhibited > 1000-fold specificity for AMPDA relative to adenosine deaminase.
