854935-60-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 854935-60-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,4,9,3 and 5 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 854935-60:
(8*8)+(7*5)+(6*4)+(5*9)+(4*3)+(3*5)+(2*6)+(1*0)=207
207 % 10 = 7
So 854935-60-7 is a valid CAS Registry Number.

, p. 4560 - 4562 (2007/10/03)
The use of PPE4 as a selective and sensitive material to detect lead(II) ions in water was discussed. The reaction of 2,5-diiodo-hydroquinone reaction with 2-bromoethyl acetate in butanone in the presence of potassium carbonate yileded the ester. The quen
