Check Digit Verification of cas no
The CAS Registry Mumber 728878-73-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,8,8,7 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 728878-73:
(8*7)+(7*2)+(6*8)+(5*8)+(4*7)+(3*8)+(2*7)+(1*3)=227
227 % 10 = 7
So 728878-73-7 is a valid CAS Registry Number.

Intramolecular chromium(II)-catalyzed pinacol cross coupling of 2-methylene-α,ω-dicarbonyls
Groth, Ulrich,Jung, Marc,Vogel, Till
, p. 1054 - 1058 (2007/10/03)
Using only 10% of CrCl2 as catalyst, manganese-powder as reducing agent and TMSC1 as scavenger, 2-methylene-α,ω-dialdehydes and -ketones can be coupled to form cyclic diols diastereoselectively. The diastereomeric excess strongly depends on the ring size and the substituents of the ω-carbonyl group. The greater the ring size the higher diastereoselectivities are observed. In all cases cis-diols are preferentially formed.
