Check Digit Verification of cas no
The CAS Registry Mumber 242130-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,2,1,3 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 242130-33:
(8*2)+(7*4)+(6*2)+(5*1)+(4*3)+(3*0)+(2*3)+(1*3)=82
82 % 10 = 2
So 242130-33-2 is a valid CAS Registry Number.

Synthesis of β-glucuronides of estradiol, ethynylestradiol and estrone
Werschkun, Barbara,Gorziza, Karin,Thiem, Joachim
, p. 629 - 637 (2007/10/03)
Improved syntheses for the 3-β-D-glucuronides of the steroidal sex hormones 17β-estradiol, 17α-ethynylestradiol and estrone are reported employing boron trifluoride diethyl etherate catalysis with tetraacetylated glucuronic acid or the corresponding imidate.
