124853-67-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124853-67-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,8,5 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 124853-67:
(8*1)+(7*2)+(6*4)+(5*8)+(4*5)+(3*3)+(2*6)+(1*7)=134
134 % 10 = 4
So 124853-67-4 is a valid CAS Registry Number.

Hong, Seongkuk,Chang, Kyeongho,Ku, Bonchul,Oh, Dong Young
, p. 3307 - 3308 (2007/10/02)
A new synthetic route to β-keto phosphonates from diethyl 1-(trimethylsilyl)vinylphosphonate 1 is described.This involves nucleophilic addition of the organolithium reagents toward 1 followed by quenching with acid chlorides and alkyl isocyanates.
