Check Digit Verification of cas no
The CAS Registry Mumber 185759-00-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,7,5 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 185759-00:
(8*1)+(7*8)+(6*5)+(5*7)+(4*5)+(3*9)+(2*0)+(1*0)=176
176 % 10 = 6
So 185759-00-6 is a valid CAS Registry Number.

Page 36, (2008/06/13)
Ortho esters and ortho carbonates can be produced by alkylating esters and carbonates with, for example, the hexafluorophosphate salt of a trialkyl oxonium ion. The spiro species are useful intermediates in the synthesis of complex organic molecules. Synt
