Check Digit Verification of cas no

The CAS Registry Mumber 1834-03-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,3 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1834-03:
(6*1)+(5*8)+(4*3)+(3*4)+(2*0)+(1*3)=73
73 % 10 = 3
So 1834-03-3 is a valid CAS Registry Number.

Lewis acid base chemistry of Bestmann's ylide, Ph3PCCO, and its bulkier analogue, (cyclohexyl)3PCCO

Brar, Amandeep,Unruh, Daniel K.,Aquino, Adelia J.,Krempner, Clemens

, p. 3513 - 3516 (2019)

The new phosphoranylideneketene, (cyclohexyl)3PCCO, was synthesized and structurally as well as spectroscopically characterized. Ph3PCCO and (cyclohexyl)3PCCO were found to be weak ambidentate Lewis bases capable of donating to strong Lewis acids via the ylidic carbon or the carbonyl oxygen.
