Check Digit Verification of cas no

The CAS Registry Mumber 247035-43-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,0,3 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 247035-43:
(8*2)+(7*4)+(6*7)+(5*0)+(4*3)+(3*5)+(2*4)+(1*3)=124
124 % 10 = 4
So 247035-43-4 is a valid CAS Registry Number.

(2S)-Benzeneslfonylamino-3-[3-methoxy-4-{4-(1,4,5,6-tetrahydropyrimidin-2- ylamino)piperidin-1-yl}benzoylamino]propionic acid, MN-447, is a potent antagonist of the integrins αvβ33 and αIIbβ3 Herein, we report a novel synthetic protocol that produces MN-447 in an overall yield of 45%. This protocol, when compared with the original synthetic route for MN-447, is more cost-effective, requires fewer steps, does not require chromatographic purification of intermediates and MN-447, and increases the overall yield by 35%. This report focuses on the synthetic strategies that were developed for this protocol. Now, the large quantities of MN-447 that are needed for preclinical and toxicological studies can be readily obtained.
