Check Digit Verification of cas no

The CAS Registry Mumber 129031-91-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,3 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129031-91:
(8*1)+(7*2)+(6*9)+(5*0)+(4*3)+(3*1)+(2*9)+(1*1)=110
110 % 10 = 0
So 129031-91-0 is a valid CAS Registry Number.

Synthetic and Kinetic Studies of the Intramolecular Diels-Alder Reactions of Cycloalkenylallenylphosphine Oxides

Curtin, Michael L.,Okamura, William H.

, p. 5278 - 5287 (2007/10/02)

Kinetic investigations reveal that diphenylphosphinoyl (diphenylphosphine oxide) substituted cycloalkenylallenes 13b-d undergo intramolecular Diels-Alder (IMDA) cyclizations at room temperature to afford adducts with gem-dialkyl effect accelerations of 4.
