Check Digit Verification of cas no

The CAS Registry Mumber 119561-14-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,5,6 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 119561-14:
(8*1)+(7*1)+(6*9)+(5*5)+(4*6)+(3*1)+(2*1)+(1*4)=127
127 % 10 = 7
So 119561-14-7 is a valid CAS Registry Number.

EFFECT OF THE NATURE AND POSITION OF SUBSTITUENTS IN THE AROMATIC RING ON CATALYTIC REARRANGEMENT OF 1,3-BIS(2-CHLOROPHENOXY) AND 1,3-BIS(4-CHLOROPHENOXY)-2-METHYLENEPROPANES

Krasnov, V. A.,Levashova, V. I.,Bunina-Krivorukova, L. I.

, p. 954 - 958 (2007/10/02)

Unlike the thermal rearrangement, the catalytic rearrangement of 1,3-bis(2-chlorophenoxy)- and 1,3-bis(4-chlorophenoxy)-2-methylenepropanes (Ia, b) takes place by an intermolecular mechanism with the participation of only one O-C bond and subsequent cyclization of the obtained ether phenols to coumarans; rearrangement is faster in the case of the 2-chloro-substituted ether.The subsequent participation of the two O-C bonds in the isomerization is observed in the case of 1,3-bis(2,4-dichlorophenoxy)-2-methylenepropane on account of the retarded cyclization.
