Check Digit Verification of cas no

The CAS Registry Mumber 1204430-32-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,4,3 and 0 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1204430-32:
(9*1)+(8*2)+(7*0)+(6*4)+(5*4)+(4*3)+(3*0)+(2*3)+(1*2)=89
89 % 10 = 9
So 1204430-32-9 is a valid CAS Registry Number.

An efficient and recyclable catalyst for the cleavage of tert-butyldiphenylsilyl ethers

Yan, Shiqiang,Ding, Ning,Zhang, Wei,Wang, Peng,Li, Yingxia,Li, Ming

, p. 6 - 20 (2012/07/13)

An efficient, chemoselective, and environment-friendly method for the deprotection of tert-butyldiphenylsilyl ethers mediated by triflic acid supported on silica gel is reported. A wide range of tert-butyldiphenylsilyl ethers derived from carbohydrate and saponin residues can be smoothly cleaved in the presence of various types of other protecting groups in good to excellent yields in acetonitrile. This heterogeneous reaction does not require aqueous workup, and the supported catalyst can be readily recycled.
