Check Digit Verification of cas no

The CAS Registry Mumber 57409-55-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,4,0 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 57409-55:
(7*5)+(6*7)+(5*4)+(4*0)+(3*9)+(2*5)+(1*5)=139
139 % 10 = 9
So 57409-55-9 is a valid CAS Registry Number.

Bromination of alkenols with the H2O2 - LiBr - CeIII and H2O2 - LiBr - CeIV systems

Nikishin,Sokova,Kapustina

, p. 459 - 463 (2013/07/05)

Reactions of alkenols with H2O2 - LiBr - Ce(NO 3)3·6H2O or H2O2 - LiBr - Ce(NH4)2(NO3)6 system led to bromination of the double bond to yield vicinal dibromoalkanols. The reaction proceeded highly selectively, no oxidation of the hydroxyl group virtually occurred.
