Check Digit Verification of cas no

The CAS Registry Mumber 848572-80-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,8,5,7 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 848572-80:
(8*8)+(7*4)+(6*8)+(5*5)+(4*7)+(3*2)+(2*8)+(1*0)=215
215 % 10 = 5
So 848572-80-5 is a valid CAS Registry Number.

SYNTHESIS OF SODIUM NARCISTATIN AND RELATED COMPOUNDS

-

Page/Page column 17, (2008/06/13)

The present invention involves use of the compounds narciclasine (2a) and 7-deoxy-narciclasine (2c), which are obtained via isolation from the medicinal plant species Narcissus (Amaryllidaceae), as precursors in a novel synthesis method in which each of these compounds are selectively hydrogenated to produce trans-dihydronarciclasine (1a) and 7-deoxy-trans-dihydronarciclasine (1c). Also described herein is a novel synthesis method for producing sodium narcistatin (11) from narciclasine (2a). Further described herein are certain novel 3,4-cyclic phosphate prodrugs, including sodium-7-deoxynarcistatin (8), sodium-7-deoxy-transdihydronarcistatin (9), and sodium transdihydronarcistatin (10).
