115375-37-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 115375-37-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,3,7 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 115375-37:
(8*1)+(7*1)+(6*5)+(5*3)+(4*7)+(3*5)+(2*3)+(1*7)=116
116 % 10 = 6
So 115375-37-6 is a valid CAS Registry Number.

Preparation of B-ring brominated derivatives of estradiol.
Leon,Mettler,Hylarides
, p. 395 - 400 (1986)
The preparation of 6 beta-methoxy-7 alpha-bromoestradiol (1) is reported. Addition of in situ-generated BrOMe to 6-dehydroestradiol 3-tetrahydropyranyl ether (4a) afforded the expected addition product. Removal of the tetrahydropyranyl protective group was carried out by mild acid hydrolysis to afford 1 in good yields. This base-sensitive compound is chemically stable over long periods of time.
