Check Digit Verification of cas no
The CAS Registry Mumber 17938-09-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,3 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 17938-09:
(7*1)+(6*7)+(5*9)+(4*3)+(3*8)+(2*0)+(1*9)=139
139 % 10 = 9
So 17938-09-9 is a valid CAS Registry Number.

Alcohol-free: A versatile, efficient, and practical synthesis of alkoxysilanes without generation of HCl involves the reaction of chlorosilanes with unsymmetrical ethers in the presence of a Lewis acid (see scheme). The reaction proceeds through selective cleavage of C-O bonds and is superior to conventional processes. Industrially feasible reagents are used and only one by-product results. Copyright
