Originator
Boldenone
undecylenate,Shandong Xinfa
Pharmaceutical
Co., Ltd.
Manufacturing Process
To a solution 5 g of L-dehydrotestosterone in 25 ml of benzene was added 3
ml of pyridine and 7.1 ml undecylene chloride. The mixture was heated for 2
heurs at 70°C. After cooling pyridine hydrochloride was filtered off. The filtrat
was purified via chromatography on neutral aluminum oxide. Benzenic eluate
was concentrated to obtain 1-dehydrotestosteron 17-undecylenate (boldenone
undecylenate) as an oil; λmax 243-244 nm.
Therapeutic Function
Anabolic
benefits
With a chemical ?structure that's nearly identical to testosterone, boldenone can ?stimulate protein synthesis and the release of erythropoietin in the ?kidneys. Athletes sometimes use boldenone, which may be sold on the ?black market, to increase muscle mass and strength.
Mechanism of action
Boldenone
is a steroid hormone which has androgenic activity. Androgens bind to

Check Digit Verification of cas no
The CAS Registry Mumber 13103-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,0 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13103-34:
(7*1)+(6*3)+(5*1)+(4*0)+(3*3)+(2*3)+(1*4)=49
49 % 10 = 9
So 13103-34-9 is a valid CAS Registry Number.
