Check Digit Verification of cas no

The CAS Registry Mumber 118787-32-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,7,8 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 118787-32:
(8*1)+(7*1)+(6*8)+(5*7)+(4*8)+(3*7)+(2*3)+(1*2)=159
159 % 10 = 9
So 118787-32-9 is a valid CAS Registry Number.

STEREODESIGN OF CROWN ETHERS. I. SYNTHESIS AND (13)C NMR STUDY OF TRANS- CYCLOHEXANOCROWN ETHERS

Samoshin, V. V.,Zelenkina, O. A.,Subbotin, O. A.,Sergeev, N. M.,Zefirov, N. S.

, p. 413 - 418 (2007/10/02)

A series of trans-cyclohexanocrown ethers were synthesized by the intermolecular cyclization of polyethylene glycol trans-2-hydroxycyclohexyl ethers with the ditosyl derivatives of polyethylene glycols.A complete assignment of the signals in the (13)C NMR spectra was made for the obtained compounds.
