Check Digit Verification of cas no
The CAS Registry Mumber 90344-85-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,4 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90344-85:
(7*9)+(6*0)+(5*3)+(4*4)+(3*4)+(2*8)+(1*5)=127
127 % 10 = 7
So 90344-85-7 is a valid CAS Registry Number.

3-Chloro-2H-thiete 1,1-dioxide, prepared by dichlorination of thietane 1,1-dioxide followed by dehydrochlorination, reacts with carbanions, amines, alcohols, and thiols to give 3-substituted thietane or 2H-thiete 1,1-dioxides.For example, reaction with the anion of dimethyl or diethyl malonate gives 3-thietane 1,1-dioxide. 3-Chloro-2H-thiete 1,1-dioxide also undergoes Diels-Ader reactions with butadiene and 1,3-diphenylisobenzofuran. 2,3-Dibromothietane 1,1-dioxide, 2,3-dibromo-3-chlorothietane 1,1-dioxide, 2-bromo-2H-thiete 1,1-dioxide, and 2-bromo-3-chloro-2H-thiete 1,1-dioxide also have been prepared.
