Check Digit Verification of cas no

The CAS Registry Mumber 250613-67-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,0,6,1 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 250613-67:
(8*2)+(7*5)+(6*0)+(5*6)+(4*1)+(3*3)+(2*6)+(1*7)=113
113 % 10 = 3
So 250613-67-3 is a valid CAS Registry Number.

Silver(I)-catalyzed addition of zirconocenes to epoxy esters: A new entry to 1,4-dicarbonyl compounds and pyridazinones

Wipf, Peter,Methot, Joey-Lee

, p. 1253 - 1255 (1999)

(matrix presented) The Ag(I)-catalyzed tandem epoxy ester rearrangement-dioxycarbenium ion addition reaction with alkenyl zirconocenes provides 1,4-keto esters that can be further converted to substituted pyridazinones. The use of a fluorous tag in a cyclization-assisted cleavage strategy demonstrates the feasibility of extending this methodology to high-throughput organic synthesis.
