284663-71-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 284663-71-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,4,6,6 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 284663-71:
(8*2)+(7*8)+(6*4)+(5*6)+(4*6)+(3*3)+(2*7)+(1*1)=174
174 % 10 = 4
So 284663-71-4 is a valid CAS Registry Number.

Symmetric bisthiiranes were synthesized by reactions of the corresponding bisoxiranes with thiourea in the presence of methyl alcohol. The initial bisoxiranes were obtained by cyclization of bis(chlorohydrins) which were prepared by reaction of p-phenylen
