Check Digit Verification of cas no

The CAS Registry Mumber 1338091-82-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,0,9 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1338091-82:
(9*1)+(8*3)+(7*3)+(6*8)+(5*0)+(4*9)+(3*1)+(2*8)+(1*2)=159
159 % 10 = 9
So 1338091-82-9 is a valid CAS Registry Number.

Solvent-free synthesis of hydrazones and their subsequent N-alkylation in a Ball-mill

Nun, Pierrick,Martin, Charlotte,Martinez, Jean,Lamaty, Frédéric

, p. 8187 - 8194 (2011)

A large variety of Boc-, Bz-, Ts-, and Fmoc- protected hydrazones were prepared via condensation of an equimolar amount of carbonyl-compound and the corresponding hydrazine using a ball-mill. Hydrazones were always obtained in a quantitative yield and no solvents were used at any step. In a second step, we realized the first solvent-free N-allylation and N-benzylation of these hydrazones.
