850403-52-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 850403-52-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,4,0 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 850403-52:
(8*8)+(7*5)+(6*0)+(5*4)+(4*0)+(3*3)+(2*5)+(1*2)=140
140 % 10 = 0
So 850403-52-0 is a valid CAS Registry Number.

New synthetic route to 3-furylphosphonates
Lee, Chi-Wan,Oh, Dong Young
, p. 1171 - 1174 (2007/10/03)
A method for the preparation of 3-furylphosphonates has been developed starting with the addition of homoallylic phosphonates to nitrile, followed by a sequence consisting of acidic hydrolysis, iodine-mediated cyclization and dehydroiodination by DBU.
