Check Digit Verification of cas no

The CAS Registry Mumber 319459-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,9,4,5 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 319459-65:
(8*3)+(7*1)+(6*9)+(5*4)+(4*5)+(3*9)+(2*6)+(1*5)=169
169 % 10 = 9
So 319459-65-9 is a valid CAS Registry Number.

A novel synthetic route to ethyl 3-substituted-trans-2,3-difluoro-2-acrylates and their reactions with nucleophiles

Zhang,Lu

, p. 8545 - 8548 (2000)

Reaction of a variety of trans-1-trimethylsilyl-1,2-difluoroalkenes with ethyl chloroformate in the presence of potassium fluoride gave the corresponding ethyl 3-substituted-trans-2,3-difluoro-2-acrylates in good yields, which reacted with a variety of nucleophiles such as hydrazine hydrate, amidines and thiourea etc. in the presence of bases to afford the corresponding 4-fluoropyrazole, 5-fluoropyrimidine and 5-fluoro-2-uracil derivatives in good yields.
