Check Digit Verification of cas no
The CAS Registry Mumber 18148-74-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,1,4 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 18148-74:
(7*1)+(6*8)+(5*1)+(4*4)+(3*8)+(2*7)+(1*4)=118
118 % 10 = 8
So 18148-74-8 is a valid CAS Registry Number.

Synthesis and characterization of mono-, bis-, tris-, and tetrakis(trimthylsilylmethyl)silanes: (Me3SiCH2)xSiH4-x (x = 1-4)
Whitmarsh, Chris K.,Interrante, Leonard V.
, p. 69 - 77 (2007/10/02)
The mono-, bis-, tris, and tetrakis(trimethylsilylmethyl)silanes, (Me3SiCH2)xSiH4-x(x = 1-4), have been prepared for use as "models" of the various Si-centered functional units in a complex, highly branched polycarbosilane polymer of the approximate composition, "(SiH2CH2)n".These compounds have been characterized by GC, IR, 1H, 13C, 29Si NMR, MS, and elemental analysis.The IR and NMR data for this series of compounds show distinct trends on increasing substitution, which are related to the structural differences within the series.
