Check Digit Verification of cas no
The CAS Registry Mumber 56665-79-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,6,6 and 5 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 56665-79:
(7*5)+(6*6)+(5*6)+(4*6)+(3*5)+(2*7)+(1*9)=163
163 % 10 = 3
So 56665-79-3 is a valid CAS Registry Number.

A regioselective PCl5 mediated dehydration for preparing Δ9,11 corticosteroids
Fu, Xiaoyong,Tann, Chou-Hong,Thiruvengadam,Lee, Junning,Colon, Cesar
, p. 2639 - 2642 (2001)
A regioselective PCl5-induced dehydration of 11α-hydroxy corticosteroids was invented to provide the corresponding Δ9,11 double bond trienes in excellent yield (>90%) with 99:1 regioisomeric ratio to the Δ11,12 isomers. A syn-elimination mechanism was proposed for this reaction.
