Check Digit Verification of cas no

The CAS Registry Mumber 16987-38-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,8 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 16987-38:
(7*1)+(6*6)+(5*9)+(4*8)+(3*7)+(2*3)+(1*8)=155
155 % 10 = 5
So 16987-38-5 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.
