100642-98-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 100642-98-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,6,4 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 100642-98:
(8*1)+(7*0)+(6*0)+(5*6)+(4*4)+(3*2)+(2*9)+(1*8)=86
86 % 10 = 6
So 100642-98-6 is a valid CAS Registry Number.

, p. 366 - 367 (2000)
Length-defined organic solvent soluble oligo-L-leucines containing an Aib residue were prepared by stepwise elongation and fragment condensation methods, and were used as catalysts in the Julia-Colonna asymmetric epoxidation reaction. The yield and enanti
