Check Digit Verification of cas no

The CAS Registry Mumber 111143-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,1,4 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 111143-98:
(8*1)+(7*1)+(6*1)+(5*1)+(4*4)+(3*3)+(2*9)+(1*8)=77
77 % 10 = 7
So 111143-98-7 is a valid CAS Registry Number.

PERMETHYLMETALLOCENE. V. REAKTIONEN DES DECAMETHYLRUTHENICENIUM-KATIONS

Koelle, U.,Grub, J.

, p. 133 - 140 (2007/10/02)

The novel decamethylruthenicenium cation + undergoes a facile deprotonation/oxidation reaction to yield a tetramethylfulvene cation *C5Me4-exo-CH2>+ (Cp*=η5-C5Me5), +, together with neutral 1.The reaction is promoted by weakly coordinating Lewis bases such as Cl-. + is also generated by hydride abstraction from 1 with Ph3CBF4.Addition of nucleophiles Nu to + gives neutral complexes RuCp*C5Me4CH2Nu (Nu=R2NH, ROH or OH-).The mechanism of formation of + is discussed with reference to electrochemically evaluated redox properties of the species involved.
