161887-11-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161887-11-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,8,8 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 161887-11:
(8*1)+(7*6)+(6*1)+(5*8)+(4*8)+(3*7)+(2*1)+(1*1)=152
152 % 10 = 2
So 161887-11-2 is a valid CAS Registry Number.

, p. 2605 - 2609 (2007/10/02)
Chiral 5,5-disubstituted N-acyloxymethylbarbiturates have been obtained in 40-99% optical yields by lipase-catalyzed hydrolyses of 5,5-disubstituted N,N'-bisacyloxymethylbarbiturates in H2O-saturated diisopropyl ether. These chiral barbiturates
