171196-77-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 171196-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,1,9 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 171196-77:
(8*1)+(7*7)+(6*1)+(5*1)+(4*9)+(3*6)+(2*7)+(1*7)=143
143 % 10 = 3
So 171196-77-3 is a valid CAS Registry Number.

Yus, Miguel,Foubelo, Francisco,Falvello, Larry R.
, p. 2081 - 2092 (2007/10/03)
Lithiation of chiral allylamine (R)-1 with BunLi and ButLi leads to the formation of intermediate (R)-2, which by reaction with D2O, Me2CO or (CH2)5CO affords the expected chiral compounds (R)-3, (R)-4 and (R)-5, respectively.With Bu
