Check Digit Verification of cas no
The CAS Registry Mumber 128425-67-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,2 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128425-67:
(8*1)+(7*2)+(6*8)+(5*4)+(4*2)+(3*5)+(2*6)+(1*7)=132
132 % 10 = 2
So 128425-67-2 is a valid CAS Registry Number.

STRAINED OXIRANES FROM CIS-DIOLS
Palomino, Eduardo,Schaap, A. Paul,Heeg, Mary Jane
, p. 6797 - 6800 (1989)
Cis-diols of some strained molecules are converted to epoxides without inversion of configuration by the use of the redox system triphenylphosphine: diethylazocarboxylate, or by treatment of their dimethylaminodioxolane derivatives with trifluoroacetic anhydride as catalyst.
