Check Digit Verification of cas no

The CAS Registry Mumber 91425-08-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,4,2 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91425-08:
(7*9)+(6*1)+(5*4)+(4*2)+(3*5)+(2*0)+(1*8)=120
120 % 10 = 0
So 91425-08-0 is a valid CAS Registry Number.

The sp3-Carbon-Attached Trimethylsilyl Group as Removable Asymmetry-Inducing Auxiliary. 1. Aromatic Resin Acid Ring Systems

Janssen, Cornelus G. M.,Godefroi, Erik F.

, p. 3600 - 3603 (1984)

The use of the trimethylsilyl (Me3Si) unit as detachable diastereoselectivity-inducing auxiliary during cationic polycyclization reactions has been examined.Model studies show 2a,b to be easily cyclized to 3a-c in CF3COOH-containing CH2Cl2.Polycyclization of 5a, on treatment with SnCl4 in CH2Cl2, gives a 85:15 ratio of 6a/7a.The same conditions transform 5b into 5percent of 100percent diastereoselectively ortho-cyclized 6b and 46percent of para-cyclized 6c/7c, occurring as a 77:23 epimeric mixture.Desilylation of the cyclized materials, using KO-t-Bu/Me2SO, provides 4a-c and 8a,c.
