Check Digit Verification of cas no

The CAS Registry Mumber 1454890-28-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,4,8,9 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1454890-28:
(9*1)+(8*4)+(7*5)+(6*4)+(5*8)+(4*9)+(3*0)+(2*2)+(1*8)=188
188 % 10 = 8
So 1454890-28-8 is a valid CAS Registry Number.

Synthesis and biological evaluation of prodigiosene conjugates of porphyrin, estrone and 4-hydroxytamoxifen

Hawco, Cassandra L.A.,Marchal, Estelle,Uddin, Md. Imam,Baker, Alexander E.G.,Corkery, Dale P.,Dellaire, Graham,Thompson, Alison

, p. 5995 - 6002 (2013)

To generate the first series of prodigiosene conjugates, the tripyrrolic skeleton was appended to estrone, tamoxifen and porphyrin frameworks by way of ester linkers and various hydrocarbon chain lengths. The ability of the conjugates to inhibit various types of cancer cells was evaluated in vitro. The porphyrin conjugates did not exhibit significant activity. The estrone conjugates exhibited modest activity, for the most part. However, significantly greater growth inhibition activity against certain breast, colon, lung, leukemia, melanoma and prostate cell lines was noted. This unusual effect for this first generation model class of compound warrants further investigation and comparison to cases where estrogens are linked to prodigiosenes via connection points that do not feature in estrogen receptor binding. The 4-hydroxytamoxifen conjugates exhibit nanomolar range activity against the MCF-7 breast cancer cell line, paving the way to expand the scope and connectivity of prodigiosene-tamoxifen conjugates.
