Check Digit Verification of cas no

The CAS Registry Mumber 300543-15-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,0,5,4 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 300543-15:
(8*3)+(7*0)+(6*0)+(5*5)+(4*4)+(3*3)+(2*1)+(1*5)=81
81 % 10 = 1
So 300543-15-1 is a valid CAS Registry Number.

Unprecedented effects of the trimethylsilyl group on the reactivity of 3C-silylated silacyclopentenes and their derivatives

Boukherroub, Rabah,Manuel, Georges

, p. 141 - 149 (2000)

We have synthesised new 3C-silylated silacyclopentenes from the corresponding 3-trimethylsilyl-1,1-dichloro-1-silacyclopent-3-enes. The presence of two metal centres M (M = Si) in α and β-positions confers an original structure for these new heterocycles. The chemical behaviour of such compounds and their derivatives was studied and compared to the results obtained in the non-substituted silacyclopentane series.
