Check Digit Verification of cas no
The CAS Registry Mumber 74912-05-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,1 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74912-05:
(7*7)+(6*4)+(5*9)+(4*1)+(3*2)+(2*0)+(1*5)=133
133 % 10 = 3
So 74912-05-3 is a valid CAS Registry Number.

, p. 572 - 583 (2007/10/02)
The synthesis of (-) and (+) nonactic acids (2a) and (2b) has been achieved starting from D-mannose (7) and D-gluono-γ-lactone (22) respectively.The key step in the synthesis is the -sigmatropic rearrangement of the silylated ketene-acetals IV leadin
