138548-38-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138548-38-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,4 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138548-38:
(8*1)+(7*3)+(6*8)+(5*5)+(4*4)+(3*8)+(2*3)+(1*8)=156
156 % 10 = 6
So 138548-38-6 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
