129678-94-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129678-94-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,6,7 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 129678-94:
(8*1)+(7*2)+(6*9)+(5*6)+(4*7)+(3*8)+(2*9)+(1*4)=180
180 % 10 = 0
So 129678-94-0 is a valid CAS Registry Number.

, p. 6135 - 6139 (1990)
Three new hepatotoxic cyclic heptapeptides in the microcystin class were isolated from the cyanobacterium (blue-green alga) Nostoc sp. strain 152 and assigned structures based on their high-resolution FABMS, FABMS/MS, 1H and 13C NMR spectra, amino acid an
