Check Digit Verification of cas no

The CAS Registry Mumber 81685-38-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,8 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81685-38:
(7*8)+(6*1)+(5*6)+(4*8)+(3*5)+(2*3)+(1*8)=153
153 % 10 = 3
So 81685-38-3 is a valid CAS Registry Number.

BASE-CATALYZED OLIGOMERIZATION OF LEVOGLUCOSENONE

Shafizadeh, Fred,Furneaux, Richard H.,Pang, David,Stevenson, Thomas T.

, p. 303 - 314 (2007/10/02)

Heating levoglucosenone in aqueous triethylamine gives a dimer and two trimers in yields of 8, 18, and 56percent, respectively.These compounds have been isolated crystalline, and their structures and stereochemistry have been investigated by (13)C- and (1)H-n.m.r. and other spectroscopic methods.These data indicate that the dimer is apparently formed by Michael addition to provide a C-3-C-4-linked, cyclic trimer and an olefinic, cyclic trimer containing two C-3-C-4 linkages and one C-2-C-3 linkage.
