129012-22-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 129012-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,1 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 129012-22:
(8*1)+(7*2)+(6*9)+(5*0)+(4*1)+(3*2)+(2*2)+(1*2)=92
92 % 10 = 2
So 129012-22-2 is a valid CAS Registry Number.

INTRAMOLECULAR CONDENSATION OF STEROIDAL 17α-FORMYL 17β-ACETATES: SYNTHESIS OF 14-FUNCTIONALISED 17-SPIROLACTONES

Bull, James R.,Steer, Lynne M.,Dillen, Jan L. M.

, p. 5401 - 5412 (2007/10/02)

17β-Acetoxy-3-methoxyestra-1,3,5(10)-triene-14,17α-dicarbaldehyde (1) undergoes base-mediated intramolecular condensation to give a mixture of the (141R)- and (141S)-141,20-hemiacetals of (20R)-14-formyl-20-hydroxy-3-methoxy-19-nor-17α-pregna-1,3,5(10)-triene-21,17-carbolactone (2).The synthesis of derived 19-nor-17-spirolactones is described, and it is shown that 14-functionality participates in unusual intramolecular rearrangements.
