Check Digit Verification of cas no

The CAS Registry Mumber 947747-31-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,7,7,4 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 947747-31:
(8*9)+(7*4)+(6*7)+(5*7)+(4*4)+(3*7)+(2*3)+(1*1)=221
221 % 10 = 1
So 947747-31-1 is a valid CAS Registry Number.

Concise syntheses of immunostimulating glycolipids, α-galactosyl ceramides

Tsujimoto, Takashi,Ito, Yukishige

, p. 5513 - 5516 (2008/02/10)

α-Galactosylceramides (α-GalCers) are well known as immunostimulating agents having therapeutic potential. To facilitate the synthesis of α-GalCers and their derivatives, a novel and convergent strategy was designed, which is expected to be versatile for the preparation of a variety of analogues in a diversity-oriented fashion. As an initial demonstration of our strategy, KRN7000 and OCH were synthesized in eight steps from a common intermediate, which is easily obtainable in a multi-gram scale.
