219908-87-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219908-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,9,0 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 219908-87:
(8*2)+(7*1)+(6*9)+(5*9)+(4*0)+(3*8)+(2*8)+(1*7)=169
169 % 10 = 9
So 219908-87-9 is a valid CAS Registry Number.

1,3-Dithiane polymers for the supported synthesis of ketones
Bertini, Vincenzo,Lucchesini, Francesco,Pocci, Marco,De Munno, Angela
, p. 9263 - 9266 (2007/10/03)
The synthesis of polymeric reagents containing an odorless propane-1,3- dithiol functionality is reported. Their usefulness for the solid phase synthesis of ketones via the umpoled alkylation of 1,3-dithianes is demonstrated.
