Check Digit Verification of cas no

The CAS Registry Mumber 1333925-55-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,9,2 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1333925-55:
(9*1)+(8*3)+(7*3)+(6*3)+(5*9)+(4*2)+(3*5)+(2*5)+(1*5)=155
155 % 10 = 5
So 1333925-55-5 is a valid CAS Registry Number.

A mild ligand-free iron-catalyzed liberation of alcohols from allylcarbonates

Dieskau, Andre P.,Plietker, Bernd

supporting information; experimental part, p. 5544 - 5547 (2011/12/05)

Different from most carbonates the allyloxy carbonyl protecting group can be cleaved under neutral conditions using metal catalysis. However, most of the catalysts employed to date are based upon precious metals. Herein we present two protocols for the mild Fe-catalyzed liberation of alcohols from allylcarbonates that are characterized by broad functional group tolerance and exclusive chemoselectivity.
