146479-72-3 Usage
Description
Follitropin beta is a human FSH preparation of rDNA origin, which differs chemically from
natural FSH and follitropin alfa only by slight variances in the composition of the carbohydrate
side chains. In fact, the primary and tertiary structures of both follitropins alfa and beta are
indistinguishable from those of human FSH of natural origin. Furthermore, bioassays and
physiochemical studies indicate that follitropins alfa and beta are indistinguishable from each
other. Therefore, it is not surprising that follitropin beta is approved for the same medical uses
as follitropin alpha.
Check Digit Verification of cas no
The CAS Registry Mumber 146479-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,4,7 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 146479-72:
(8*1)+(7*4)+(6*6)+(5*4)+(4*7)+(3*9)+(2*7)+(1*2)=163
163 % 10 = 3
