Check Digit Verification of cas no

The CAS Registry Mumber 1253394-27-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,3,9 and 4 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1253394-27:
(9*1)+(8*2)+(7*5)+(6*3)+(5*3)+(4*9)+(3*4)+(2*2)+(1*7)=152

New synthesis of 3-trifluoromethylpyrroles by condensation of mesoionic 4-trifluoroacetyl-1,3-oxazolium-5-olates with phosphorus ylides

Saijo, Ryosuke,Hagimoto, Yuri,Kawase, Masami

supporting information; experimental part, p. 4776 - 4779 (2011/01/03)

Mesoionic 4-trifluoroacetyl-1,3-oxazolium-5-olates (1), obtained from the reaction of N-acyl-N-alkylglycines with trifluoroacetic anhydride, react with phosphorus ylides to give β-trifluoromethylpyrroles (2) in good yields. The novel ring transformations
