137255-20-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137255-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,5 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137255-20:
(8*1)+(7*3)+(6*7)+(5*2)+(4*5)+(3*5)+(2*2)+(1*0)=120
120 % 10 = 0
So 137255-20-0 is a valid CAS Registry Number.

Grover,Dwivedy,Singh,Ray,Singh,Kamboj
, p. 477 - 480 (2007/10/02)
12 new C-7 aryl- and allyl-substituted androst-5-ene derivatives were synthesized, characterized, and were screened for anti-implantation activity in rats. 10 compounds were constructed by linking the aryl/allyl magnesium bromide with 3-beta, 17-beta-diac
