Check Digit Verification of cas no

The CAS Registry Mumber 190186-24-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,1,8 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 190186-24:
(8*1)+(7*9)+(6*0)+(5*1)+(4*8)+(3*6)+(2*2)+(1*4)=134
134 % 10 = 4
So 190186-24-4 is a valid CAS Registry Number.

Preparation of 2-deoxyaldoses from aldose phenylhydrazones

Jorgensen, Christel,Pedersen, Christian

, p. 307 - 310 (2007/10/03)

Acetylation of D-mannose phenylhydrazone gives acetylated D-arabino-1-phenyl-azo-1-(E)-hexene. Subsequent reduction with sodium borohydride produces 2-deoxy-D-arabino-hexose phenylhydrazone which, on hydrolysis, gives 2-deoxy-D-arabino-hexose. By a similar procedure 2-deoxy-D-lyxo-hexose, 2,6-dideoxy-L-arabino-hexose, and 2-deoxy-D-erythropentose can be prepared from D-galactose, L-rhamnose, and D-arabinose, respectively.
