Check Digit Verification of cas no

The CAS Registry Mumber 917242-54-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,2,4 and 2 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 917242-54:
(8*9)+(7*1)+(6*7)+(5*2)+(4*4)+(3*2)+(2*5)+(1*4)=167
167 % 10 = 7
So 917242-54-7 is a valid CAS Registry Number.

Synthesis and properties of azole-substituted ferrocenes

Mochida, Tomoyuki,Shimizu, Hirotaka,Suzuki, Shinya,Akasaka, Takahiro

, p. 4882 - 4889 (2007/10/03)

4-Ferrocenyltriazole, 4-(4-ferrocenylphenyl)triazole, 4-ferrocenyltetrazole, and 4-(4-ferrocenylphenyl)tetrazole have been prepared. Redox potentials and decomposition temperatures were evaluated and all the compounds were crystallographically characterized; in most cases, weak intermolecular CH?N hydrogen bonds (H?N dist. = 2.3-2.5 ?) were formed between the azole moieties. Two polymorphs were found for 4-ferrocenyltetrazole, formed with either CH?N or π-π interactions.
