213467-20-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 213467-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,4,6 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 213467-20:
(8*2)+(7*1)+(6*3)+(5*4)+(4*6)+(3*7)+(2*2)+(1*0)=110
110 % 10 = 0
So 213467-20-0 is a valid CAS Registry Number.

Selective deprotection strategies to N-(α-methylbenzyl)-β-amino esters and derived β-lactams
Davies, Stephen G.,Ichihara, Osamu
, p. 6045 - 6048 (1998)
A variety of N,N-diprotected β-amino esters, prepared by highly diastereoselective conjugate addition of chiral lithium amides, were selectively mono-deprotected under either reductive (hydrogenolysis) or oxidative (DDQ or CAN) conditions. Combined with t
