Check Digit Verification of cas no

The CAS Registry Mumber 194421-60-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,4,2 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 194421-60:
(8*1)+(7*9)+(6*4)+(5*4)+(4*2)+(3*1)+(2*6)+(1*0)=138
138 % 10 = 8
So 194421-60-8 is a valid CAS Registry Number.

Haem d1: Development of a new coupling procedure leading to the synthesis of isobacteriochlorins

Mackman, Richard L.,Micklefield, Jason,Block, Michael H.,Leeper, Finian J.,Battersby, Alan R.

, p. 2111 - 2122 (2007/10/03)

A new approach has been developed for construction of the western and eastern lactams, e.g. 2 and 3, needed for synthesis of isobacteriochlorins. It involves acylation of pyrroles with lactonic acids to form ketones. These are then efficiently converted into the desired lactams by a short sequence of reactions. All the steps are high yielding and simple to carry out.
