Check Digit Verification of cas no

The CAS Registry Mumber 80351-84-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,5 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 80351-84:
(7*8)+(6*0)+(5*3)+(4*5)+(3*1)+(2*8)+(1*4)=114
114 % 10 = 4
So 80351-84-4 is a valid CAS Registry Number.

NOVEL REARRANGEMENTS OF α-N-ALKYLAMIDO-SUBSTITUTED SULFIDES AND SULFONES

Ishikawa, Yoshiharu,Kurebayashi, Yasuo,Suzuki, Kunio,Terao, Yoshiyasu,Sekiya, Minoru

, p. 2496 - 2502 (2007/10/02)

The present paper describes novel rearrangements of α-N-alkylamido-substituted sulfides and sulfones promoted by strong bases such as NaH, lithium diisopropylamide and butyllithium, where the alkyl group linked to the sulfur migrates to the amide carbonyl carbon to give the corresponding ketones.The reactions are established as intramolecular rearrangements, and the mechanism is discussed.Keywords: - alkyl (N-alkylamido)methyl sulfide; alkyl (N-alkylamido)methyl sulfone; alkyl α-(N-alkylamido)benzyl sulfide; intramolecular rearrangement; sodium hydride; lithium diisopropylamide; butyllithium
