Check Digit Verification of cas no

The CAS Registry Mumber 90163-00-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,6 and 3 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 90163-00:
(7*9)+(6*0)+(5*1)+(4*6)+(3*3)+(2*0)+(1*0)=101
101 % 10 = 1
So 90163-00-1 is a valid CAS Registry Number.

Microwave-assisted benzyl mono- and dibromination in diethyl carbonate as environmentally friendly alternative to radical bromination in carbon tetrachloride

Pingali, Subramanya R. K.,Upadhyay, Sunil K.,Jursic, Branko S

experimental part, p. 928 - 933 (2011/05/15)

An environmentally friendly benzyl mono- and di-bromination synthetic procedure was developed that is superior to the classic carbon tetrachloride bromination procedure in both reaction time and isolated yield. This new reaction was performed in diethyl carbonate as reaction media using microwave instead of conventional heating. Both the solvent and the brominating reagent N-bromosuccinimide (prepared from succinimide obtained from the reaction mixture) are recyclable. Practically, the preparation of our target compounds was completed in less than two hours. The Royal Society of Chemistry.
