Check Digit Verification of cas no
The CAS Registry Mumber 120881-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,8,8 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 120881-31:
(8*1)+(7*2)+(6*0)+(5*8)+(4*8)+(3*1)+(2*3)+(1*1)=104
104 % 10 = 4
So 120881-31-4 is a valid CAS Registry Number.

Oxidative demercuration revisited
Hayes,Suthers,Kitching
, p. 6175 - 6179 (2000)
A procedure for oxidative demercuration utilising O2-TEMPO-NaBH4-DMF (0°) is shown to be convenient and efficient for a variety of organomercury(II)halide systems, including spiroacetal structures acquired by intramolecular hydroxy-mercuration. (C) 2000 Elsevier Science Ltd.
