28664-61-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28664-61-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,6,6 and 4 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 28664-61:
(7*2)+(6*8)+(5*6)+(4*6)+(3*4)+(2*6)+(1*1)=141
141 % 10 = 1
So 28664-61-1 is a valid CAS Registry Number.

An efficient synthesis of linear and angular furanocoumarins has been carried out starting from iodoumbelliferone derivatives. First synthesis of 6-iodoumbelliferone is described. The average yields are higher than those reported before.
