Check Digit Verification of cas no
The CAS Registry Mumber 1587-29-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,8 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1587-29:
(6*1)+(5*5)+(4*8)+(3*7)+(2*2)+(1*9)=97
97 % 10 = 7
So 1587-29-7 is a valid CAS Registry Number.

UNSATURATED COMPOUNDS. XV. LIQUID-PHASE LOW-TEMPERATURE CHLORINATION OF 2-CHLORO- AND 2,3-DICHLORO-2-BUTENES IN THE PRESENCE OF FERRIC CHLORIDE
Kaplanyan, E. E.,Mkrtchyan, A. M.,Voskanyan, E. S.
, p. 41 - 43 (2007/10/02)
The effect of anhydrous ferric chloride on the degree of normal and anomalous chlorination of 2-chloro- and 2,3-dichloro-2-butenes at low temperatures (-20 to 0 deg C) in the presence of tert-butyl pyrocatechol was investigated.It was established that the addition of ferric chloride leads to a significant decrease in the amount of anomalous chlorination products.At the same time an increase is observed in the chlorination rate of trans-2,3-dichloro-2-butene. During the chlorination of 2,3-dichloro-2-butene under the influence of ferric chloride the anomalous chlorination product 2,3,3-trichloro-1-butene isomerizes to 1,2,3-trichloro-2-butene.

The liquid-phase chlorination of 2-halogeno-2-butenes in the presence of tert-butylpyrocatechol leads to the formation of the products from an anomalous reaction (2,3-dihalogeno-1-butenes), substitution of hydrogen at the double bond (2,3-dihalogeno-2-butenes), and normal addition (2,2,3-trihalogenobutanes).The ratios of these compounds are 70:6:24 in the case of 2-chloro-2-butene and 54:7.5:38.5 in the case of 2-bromo-2-butene.During the chlorination of 2-chloro-2-butene in the presence of sodium bicarbonate the formation of 3-chloro-2-butanol (20percent) was observed as a result of the combined addition of chlorine and water.
