Check Digit Verification of cas no
The CAS Registry Mumber 1310729-91-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,0,7,2 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1310729-91:
(9*1)+(8*3)+(7*1)+(6*0)+(5*7)+(4*2)+(3*9)+(2*9)+(1*1)=129
129 % 10 = 9
So 1310729-91-9 is a valid CAS Registry Number.

An approach for the multigram synthesis of 3,3-difluorocyclobutyl-substituted building blocks (including carboxylic acid, amines, alcohols, azide, trifluoroborate ketone) is described. It is shown that, in most cases, ethyl 3,3-difluorocyclobutanecarboxylate is a convenient common synthetic intermediate to obtain the target derivatives. For preparation of 3,3-difluorocyclobutanol or -cyclobutanone, an alternative pathway via reaction of dichloroketene and tert -butyl or benzyl vinyl ether should be applied.
