102195-74-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102195-74-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,1,9 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 102195-74:
(8*1)+(7*0)+(6*2)+(5*1)+(4*9)+(3*5)+(2*7)+(1*4)=94
94 % 10 = 4
So 102195-74-4 is a valid CAS Registry Number.

, p. 2277 - 2282 (2007/10/02)
Pairs of optically pure enantiomers of substituted 1,1-diamines have been prepared from the azides of L-amino-acids via the Curtius rearrangement.This synthesis is based on the interchange of two groups attached to the asymmetrically substituted tetrahedr
