219716-18-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219716-18-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,7,1 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 219716-18:
(8*2)+(7*1)+(6*9)+(5*7)+(4*1)+(3*6)+(2*1)+(1*8)=144
144 % 10 = 4
So 219716-18-4 is a valid CAS Registry Number.

, p. 1337 - 1338 (2007/10/03)
Starting from various 4-alkylpyridines, the phenyldimethylsilyl group was introduced using their 1-acylpyridium salts and its oxidative unmasking afforded the corresponding pipecolinic acids.
