Check Digit Verification of cas no
The CAS Registry Mumber 7153-25-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,5 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7153-25:
(6*7)+(5*1)+(4*5)+(3*3)+(2*2)+(1*5)=85
85 % 10 = 5
So 7153-25-5 is a valid CAS Registry Number.

Novel vitamin D analogues
-
, (2008/06/13)
This invention relates to vitamin D analogues represented by the general formula I STR1 in which formula X stands for hydrogen, lower alkyl, halogen or hydroxy; Y stands for hydrogen or hydroxy; R1 and R2, which may be the same or different, stand for lower alkyl, optionally substituted with halogen or hydroxy with the proviso that R1 and R2 cannot both be methyl when X is other than lower alkyl, or, taken together with the carbon atom numbered 25, R1 and R2 can form a saturated or unsaturated C3 -C9 carbocyclic ring which may optionally be substituted at any possible position(s) with lower alkyl, halogen or hydroxy; R3 stands for hydrogen or lower alkyl; R4 and R5 represent either each hydrogen, or when taken together constitute a bond, with the result that a double bond connects carbon atoms numbered 22 and 23; and bioreversible derivatives thereof. The compounds of the invention have a favorable therapeutic index and are particularly useful in the treatment of human and veterinary disorders which are characterized by abnormal cell proliferation and/or cell differentiation.
