Check Digit Verification of cas no
The CAS Registry Mumber 214077-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,0,7 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 214077-89:
(8*2)+(7*1)+(6*4)+(5*0)+(4*7)+(3*7)+(2*8)+(1*9)=121
121 % 10 = 1
So 214077-89-1 is a valid CAS Registry Number.

A reaction sequence was studied for the preparation of cyclophanes 12, which contain 2,7-bis(2-phenylethenyl)naphthalene chromophores and polymethylenedioxy chains of different length. The irradiation of 12 in the presence of I2 led then, by ox
