118818-64-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118818-64-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,8,1 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 118818-64:
(8*1)+(7*1)+(6*8)+(5*8)+(4*1)+(3*8)+(2*6)+(1*4)=147
147 % 10 = 7
So 118818-64-7 is a valid CAS Registry Number.

Reactions of terf-Butyl Tetraethylphosphorodiamidite with Acetic and Trifluoroacetic Acids
Sal'keeva,Nurmagambetova,Kurmanaliev,Gazizov
, p. 183 - 186 (2003)
Reactions of tert-bulyl tetraethylphosphorodiamidite with acetic and trifluoroacetic acids involve substitution of the amido group. This process was described by a scheme beginning with protonation of phosphorus and proved by modeling separate reaction stages. A probable scheme of the proposed reactions is described.
