121618-33-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121618-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,1 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 121618-33:
(8*1)+(7*2)+(6*1)+(5*6)+(4*1)+(3*8)+(2*3)+(1*3)=95
95 % 10 = 5
So 121618-33-5 is a valid CAS Registry Number.

Mack, Helmut,Hanack, Michael
, p. 833 - 846 (2007/10/02)
A method for the preparation of 1,1-bis(trifluoromethyl)-substituted pyrethroids is described.For this purpose, 1,1-bis(trifluoromethyl)-substituted olefins 9 are prepared by an easy method from the aldehydes 17 with 2,2-dichlorohexafluoropropane (16) and
