Check Digit Verification of cas no
The CAS Registry Mumber 19653-76-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,6,5 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 19653-76:
(7*1)+(6*9)+(5*6)+(4*5)+(3*3)+(2*7)+(1*6)=140
140 % 10 = 0
So 19653-76-0 is a valid CAS Registry Number.

Identification of novel L-amino acid α-ligases through hidden markov model-based profile analysis

L-Amino acid α-ligase (Lal), catalyzing the formation of α-dipeptides from unprotected l-amino acids in an ATP-dependent manner, is used in cost-effective fermentative production of dipeptides. We searched for novel Lals by in silico screening using Hidden Markov Model-based profile analysis, and identified five novel Lals that showed low similarity and different substrate specificity from known Lals.
