229974-88-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 229974-88-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,9,9,7 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 229974-88:
(8*2)+(7*2)+(6*9)+(5*9)+(4*7)+(3*4)+(2*8)+(1*8)=193
193 % 10 = 3
So 229974-88-3 is a valid CAS Registry Number.

Chiral 1,3-diamines from a lithiated isocyanide and chiral aziridines
Kaiser, Alexander,Balbi, Miriam
, p. 1001 - 1014 (1999)
Reaction of lithiated 4-methoxybenzylisocyanide with homochiral amino acid derived N-tosyl- and N-diphenylphosphinoylaziridines proceeds diastereoselectively to provide N-protected 3-isocyanoamines. Separation of the diastereomers of these adducts or the
