Check Digit Verification of cas no
The CAS Registry Mumber 189098-29-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,0,9 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 189098-29:
(8*1)+(7*8)+(6*9)+(5*0)+(4*9)+(3*8)+(2*2)+(1*9)=191
191 % 10 = 1
So 189098-29-1 is a valid CAS Registry Number.

, (2008/06/13)
A biotechnological method is described for preparing compounds of the general formulas wherein R1 is acyl or acyloxy and R2 is a hydrogen atom or C1-10 alkyl, comprising the conversion of a lactam of the general formula by means of a hydrolase in the presence of a nucleophile and in the presence of a base in a constant pH range. Also described is the subsequent conversion of the compound of general formula I into the optically active 1-amino-4-(hydroxymethyl)-2-cyclopentene of the formula
