678142-80-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 678142-80-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,8,1,4 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 678142-80:
(8*6)+(7*7)+(6*8)+(5*1)+(4*4)+(3*2)+(2*8)+(1*0)=188
188 % 10 = 8
So 678142-80-8 is a valid CAS Registry Number.

Sureshan, Kana M.,Kiyosawa, Yoko,Han, Fushe,Hyodo, Sayuri,Uno, Yuhki,Watanabe, Yutaka

, p. 231 - 241 (2007/10/03)

Efficient methods for the resolution of various myo-inositol derivatives have been developed using O-acetylmandelic acid (OAM) as the chiral auxiliary. Various methods of introduction of the chiral auxiliary have been compared. DCC mediated coupling betwe

Synthesis of natural PI(3,4,5)P3

Watanabe, Yutaka,Nakatomi, Mitsunobu

, p. 1583 - 1586 (2007/10/03)

Natural phosphatidylinositol 3,4,5-trisphosphate which has been believed to have stearoyl and arachidonoyl groups at the sn-1 and -2 positions, respectively, has been synthesized using 1,2-O-cyclohexylidene 3,4-O-disiloxanyl-myo-inositol as the pivotal intermediate.
