Check Digit Verification of cas no
The CAS Registry Mumber 100074-67-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,0,7 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 100074-67:
(8*1)+(7*0)+(6*0)+(5*0)+(4*7)+(3*4)+(2*6)+(1*7)=67
67 % 10 = 7
So 100074-67-7 is a valid CAS Registry Number.

Synthesis of 2(5H)-furanones via oxidative ring expansion of 4-hydroxy-2-cyclobutenones
Verniest, Guido,De Kimpe, Norbert
, p. 947 - 950 (2007/10/03)
A new method to reduce cyclobutenediones towards 4-hydroxy-2-cyclobutenones was established. The latter compounds gave rise to new 5-halo-2(5H)-furanones by reaction with halogenating agents via a cationic ring-opening-ring-closure mechanism.
