Check Digit Verification of cas no
The CAS Registry Mumber 123251-09-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,2,5 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 123251-09:
(8*1)+(7*2)+(6*3)+(5*2)+(4*5)+(3*1)+(2*0)+(1*9)=82
82 % 10 = 2
So 123251-09-2 is a valid CAS Registry Number.

Synthesis of patulin and its cyclohexane analogue from furan derivatives
Tada,Ohtsu,Chiba
, p. 2167 - 2169 (2007/10/02)
Patulin, a mycotoxin from fungi of Penicillium and Aspergillis species, and its cyclohexane analogue were synthesized concisely via oxidation of furan derivatives, followed by cyclization to give a ylidenebutenolide ring.
