Check Digit Verification of cas no

The CAS Registry Mumber 90635-59-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,6,3 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 90635-59:
(7*9)+(6*0)+(5*6)+(4*3)+(3*5)+(2*5)+(1*9)=139
139 % 10 = 9
So 90635-59-9 is a valid CAS Registry Number.

Synthesis and X-Ray Crystal Structure of 1,2,3-Triphenylphosphirene

Marinetti, Angela,Mathey, Francois,Fischer, Jean,Mitschler, Andre

, p. 45 - 46 (1984)

1,2,3-Triphenylphosphirene is prepared from its P->W(CO)5 complex by a two step decomplexation procedure involving iodine and 1-methylimidazole; its X-ray crystal structure analysis shows a very strained ring (angle CPC = 41.8 deg) with no electronic delo
