87494-05-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87494-05-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,4,9 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 87494-05:
(7*8)+(6*7)+(5*4)+(4*9)+(3*4)+(2*0)+(1*5)=171
171 % 10 = 1
So 87494-05-1 is a valid CAS Registry Number.

Synthetic study on peptide antibiotic nisin. I. The synthesis of ring A
Wakamiya,Shimbo,Sano,et al.
, p. 2044 - 2049 (1983)
Synthesis of the ring A, a cyclic sulfide peptide part containing dehydroalanine residue, in peptide antibiotic nisin was successfully achieved by applications of two novel procedures. First, a sulfide ring was derived from a cyclic disulfide peptide by d
