Check Digit Verification of cas no
The CAS Registry Mumber 136307-89-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,3,0 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 136307-89:
(8*1)+(7*3)+(6*6)+(5*3)+(4*0)+(3*7)+(2*8)+(1*9)=126
126 % 10 = 6
So 136307-89-6 is a valid CAS Registry Number.

HIGHLY CONVERGENT APPROACH TO THE SYNTHESIS OF THE EPOXY-AMIDE FRAGMENT OF THE AZINOMYCINS
Moran, Edmund J.,Armstrong, Robert W.
, p. 3807 - 3810 (1991)
An efficient synthesis of the α-acyl amide fragment of the azinomycin antibiotics has been accomplished using the Passerini three-component condensation.Good diastereoselectivity was observed for a variety of isocyanide precursors.
