639476-06-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 639476-06-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,9,4,7 and 6 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 639476-06:
(8*6)+(7*3)+(6*9)+(5*4)+(4*7)+(3*6)+(2*0)+(1*6)=195
195 % 10 = 5
So 639476-06-5 is a valid CAS Registry Number.

Synthesis of a New Stable Conformationally Constrained 2,7-Anhydrosialic Acid Derivative

Liu, Ke-Gang,Zhou, Hai-Bin,Wu, Yu-Lin,Yao, Zhu-Jun

, p. 9528 - 9531 (2007/10/03)

A stereoseletive synthesis of 2,7-anhydrosialic acid derivative 18 was achieved from D-glucono-δ-lactone. A highly syn-selective addition of Grignard reagent to the N-benzylimine 8 served as a key step.
