Check Digit Verification of cas no

The CAS Registry Mumber 157887-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,8,8 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 157887-91:
(8*1)+(7*5)+(6*7)+(5*8)+(4*8)+(3*7)+(2*9)+(1*1)=197
197 % 10 = 7
So 157887-91-7 is a valid CAS Registry Number.

The Synthesis of Oxa-Analogues and Homologues of Naturally Occuring Polyamines

Lin, P. Kong Thoo,Kuksa, V. A.,Maguire, N. M.

, p. 859 - 866 (2007/10/03)

A number of polyamine oxa-analogues 14a-d, 19 have been synthesized.Spermidine oxa-analogues and homologues 14 were made from N-(aminooxypropyl)phthalimide 8a which was obtained either from the Fmoc-deprotection of N-phthalimide 4a or from the reaction between 3-bromopropylamine and N-hydroxyphthalimide, both reactions involving an unusual rearrangement mechanism.Sulphonated derivatives 9, 16, upon Mitsunobu condensation with N-protected 3-aminopropanol or N-alkylation with N-(bromoalkyl)phthalimides, afforded the fully protected spermidine and spermine oxa-analogues.Subsequent sequential deprotection gave spermidine analogues 14.Using the same strategy, spermine oxa-analogues 19 was synthesised. - Keywords: polyamines; oxa-analogues of polyamines; polyamine homologues; rearrangement; synthesis
