477191-85-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 477191-85-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,7,1,9 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 477191-85:
(8*4)+(7*7)+(6*7)+(5*1)+(4*9)+(3*1)+(2*8)+(1*5)=188
188 % 10 = 8
So 477191-85-8 is a valid CAS Registry Number.

Cyclization of Aryl Silanes with Unexpected Retention of Silicon
Fearnley, Stephen Philip,Tidwell, Michael W.
, p. 3797 - 3798 (2007/10/03)
(Matrix Presented) Intramolecular Friedel-Crafts cyclization of 2-O-benzyl ethers at a model pyranose acetal is activated by incorporation of a trimethylsilyl group, albeit via unexpected, presumably steric means.
