Check Digit Verification of cas no

The CAS Registry Mumber 209740-49-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,7,4 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 209740-49:
(8*2)+(7*0)+(6*9)+(5*7)+(4*4)+(3*0)+(2*4)+(1*9)=138
138 % 10 = 8
So 209740-49-8 is a valid CAS Registry Number.

Synthesis of unsymmetrically substituted meso-phenylporphyrins by Suzuki cross coupling reactions

Shi, Baolu,Boyle, Ross W.

, p. 1397 - 1400 (2002)

The synthesis of unsymmetrically substituted meso-phenylporphyrins by Suzuki cross coupling reactions was discussed. The problems of product contamination, due to deboronylation encountered with electron deficient boronic acids, were overcomed with the use of boronic esters. The unsymmetrically substituted triphenylporphyrins were found to be accessed via partial debromination in situ.
