Check Digit Verification of cas no
The CAS Registry Mumber 1204206-66-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,2,0 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1204206-66:
(9*1)+(8*2)+(7*0)+(6*4)+(5*2)+(4*0)+(3*6)+(2*6)+(1*6)=95
95 % 10 = 5
So 1204206-66-5 is a valid CAS Registry Number.

, p. 2075 - 2080 (2009)
The pseudo C2-symmetrical diketone 22 was efficiently constructed from furan-3,4-dimethanol (7) using a two-directional route featuring a double asymmetric dihydroxylation. Acidic hydrolysis of the cyclopentylidene acetais of 22 triggered a sel
