Check Digit Verification of cas no

The CAS Registry Mumber 52514-13-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,5,1 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 52514-13:
(7*5)+(6*2)+(5*5)+(4*1)+(3*4)+(2*1)+(1*3)=93
93 % 10 = 3
So 52514-13-3 is a valid CAS Registry Number.

A new efficient synthetic strategy for N-(dialkylamino)azacycle as a tetrasubstituted hydrazine derivative using sodium triacyloxyborohydride

Mizufune, Hideya,Yamamoto, Hiroaki,Nakamura, Minoru,Miki, Shokyo

, p. 6275 - 6280 (2008/09/21)

A new efficient and convergent method has been developed to construct a N-(dialkylamino)azacyclic system as a tetrasubstituted hydrazine via reductive alkylation of the corresponding hydrazone using sodium triacyloxyborohydride [NaBH(OCOR)3], which is tolerant of various substituents (e.g., phenol, conjugated olefin, amide, and thioamide) on the substrate and useful for organization of the N-aminoazacycle array.
