Check Digit Verification of cas no

The CAS Registry Mumber 1610688-77-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,0,6,8 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1610688-77:
(9*1)+(8*6)+(7*1)+(6*0)+(5*6)+(4*8)+(3*8)+(2*7)+(1*7)=171
171 % 10 = 1
So 1610688-77-1 is a valid CAS Registry Number.

Self-condensation of β-(isoxazol-5-yl) enamines under treatment with acetyl chloride and acids. Synthesis of novel 1,3-diisoxazolyl-1,3-dieneamines and 1,3,5-triisoxazolyl benzenes

, p. 3915 - 3923 (2014/06/09)

Two directions for self-condensation of β-(isoxazol-5-yl) enamines under treatment with either acetyl chloride or acids were found leading to new 1,3-diisoxazolyl-1,3-dieneamines and 1,3,5-triisoxazolyl benzenes. The effect of solvent, acid, temperature and the reaction time on the ratio of reaction products were investigated. Trans-E-cis configuration of prepared 1,3-diisoxazolyl-1,3-dieneamines was unambiguously confirmed by 2D NMR spectra and X-ray analysis. A new mechanism of 1,3-diisoxazolyl-1,3-dieneamines formation was proposed.
