Check Digit Verification of cas no

The CAS Registry Mumber 40193-89-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,1,9 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40193-89:
(7*4)+(6*0)+(5*1)+(4*9)+(3*3)+(2*8)+(1*9)=103
103 % 10 = 3
So 40193-89-3 is a valid CAS Registry Number.

FRAGMENTATION OF PHOSPHORANES: THE REACTION OF Δ3-PHOSPHOLENES WITH PHENANTHRAQUINONE

Hammond, Philip J.,Lloyd, John R.,Hall, C. Dennis

, p. 47 - 52 (2007/10/02)

Stereochemically pure cis- and trans-Δ3-phospholenes react with phenanthraquinone to form pentaco-ordinate adducts which, when heated, fragment to trans,-trans-hexa-2,4-diene and phosphonite.The relative rates of fragmentation of the adducts from 1-methyl and 1-aryl phospholenes are reported and discussed.
