Check Digit Verification of cas no

The CAS Registry Mumber 64714-16-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,7,1 and 4 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 64714-16:
(7*6)+(6*4)+(5*7)+(4*1)+(3*4)+(2*1)+(1*6)=125
125 % 10 = 5
So 64714-16-5 is a valid CAS Registry Number.

A new intramolecular reaction for the regioselective debenzylation or protection of alcohols

Madsen, Jacob,Bols, Mikael

, p. 3177 - 3178 (2007/10/03)

Strained benzylidene acetals such as 1 can be prepared with a new intramolecular reaction that allows the selective removal of benzyl protecting groups neighboring free OH groups, without attacking other benzyl groups. The mechanism of this reaction, which is useful for carbohydrate synthesis, probably proceeds via ionic intermediates with neighboring group participation.
