Check Digit Verification of cas no

The CAS Registry Mumber 649556-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,9,5,5 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 649556-56:
(8*6)+(7*4)+(6*9)+(5*5)+(4*5)+(3*6)+(2*5)+(1*6)=209
209 % 10 = 9
So 649556-56-9 is a valid CAS Registry Number.

Different thermal reactivity of a 1,2-thiaphospholo[a]phosphirane in free and metal carbonyl complexed form

Jikyo, Tamaki,Maas, Gerhard

, p. 2794 - 2795 (2003)

The W(CO)5 and Fe(CO)4 complexes of the bicyclic phosphirane 3,5,6,6-tetraphenyl-1-phospha-2-thiabicyclo-[3.1.0]hex-3-ene undergo a thermal 2-phenylphosphirane → dihydrophosphaisoindole ring expansion, while the free phosphirane suffers both a [2 + 1] cycloreversion and a fragmentation yielding a butadienyl sulfide.
