Check Digit Verification of cas no
The CAS Registry Mumber 453557-59-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,3,5,5 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 453557-59:
(8*4)+(7*5)+(6*3)+(5*5)+(4*5)+(3*7)+(2*5)+(1*9)=170
170 % 10 = 0
So 453557-59-0 is a valid CAS Registry Number.

A new route to 2-(5-aryl-2-furoylamido)-5-aryloxymethyl-1,3,4-thiadiazoles
Wang, Xicun,Li, Zheng,Da, Yuxia
, p. 1105 - 1111 (2002)
The 2-(5-aryl-2-furoylamido)-5-aryloxymethyl-1,3,4-thiadiazoles 41-18 are synthesized by the reaction of 5-aryl-2-furoic acids 1 with phenylsulfonyl chloride and 2-amino-5-aryloxymethyl-1,3,4-thiadiazoles 3 under phase transfer catalysis.
