Check Digit Verification of cas no
The CAS Registry Mumber 113459-63-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,4,5 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 113459-63:
(8*1)+(7*1)+(6*3)+(5*4)+(4*5)+(3*9)+(2*6)+(1*3)=115
115 % 10 = 5
So 113459-63-5 is a valid CAS Registry Number.

SYNTHESIS OF α-PHENYLSULFONYL CYCLOPENTANONES BY INTRAMOLECULAR CARBENOID CYCLIZATION OF α-DIAZO-β-KETO PHENYLSULFONES
Monteiro, Hugo J.
, p. 3459 - 3462 (1987)
Acyclic α-diazo-β-keto phenylsulfones undergo smooth intramolecular carbenoid cyclizations under rhodium (II) catalysis to afford α-phenyl sulfonyl cyclopentanones.
