Check Digit Verification of cas no

The CAS Registry Mumber 92-76-2 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 92-76:
(4*9)+(3*2)+(2*7)+(1*6)=62
62 % 10 = 2
So 92-76-2 is a valid CAS Registry Number.

Fluorescent substrates for potential use in enzyme-linked immunosorbent assay of membrane-bound nucleic acids

Fujita, Satoshi,Momiyama, Masayoshi,Kondo, Yasumitsu,Kagiyama, Naoto,Hori, Samuel H.,Toru, Takeshi

, p. 1347 - 1353 (2007/10/02)

A number of phosphorylated fluorochromes were synthesized and tested for the alkaline phosphatase-linked fluorescence assay of membrane-bound nucleic acids. 3-Hydroxy-N-2′-biphenyl-2-naphthalenecarboxamide phosphate ester (HBNP) was found to be the most suitable for the assay. Nonfluorescent HBNP is hydrolyzed by phospholipase bound to the probe DNA to the highly fluorescent 3-hydroxy-N,2′-biphenyl-2-naphthalenecarboxamide (HBN). HBN is insoluble enough in aqueous medium to precipitate on the nylon membrane. Spots containing as little as 5 fg of λ DNA can be successfully detected on the membrane with HBNP.
