121927-07-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121927-07-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,9,2 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121927-07:
(8*1)+(7*2)+(6*1)+(5*9)+(4*2)+(3*7)+(2*0)+(1*7)=109
109 % 10 = 9
So 121927-07-9 is a valid CAS Registry Number.

A series of menthyl 2-(trifluoromethyl)alkanoates were prepared by reaction of menthyl 2-(trifluoromethyl)propenoates with dialkyl- or diphenylcuprates and hydrofluorination of the menthyl 2-(difluoromethylene)alkanoates thus obtained by addition of tetra
