Check Digit Verification of cas no

The CAS Registry Mumber 143444-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,4,4 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 143444-57:
(8*1)+(7*4)+(6*3)+(5*4)+(4*4)+(3*4)+(2*5)+(1*7)=119
119 % 10 = 9
So 143444-57-9 is a valid CAS Registry Number.

SYNTHESIS OF cis-DECALIN DERIVATIVE VIA ?-ALLYLPALLADIUM INTERMEDIATE AND ITS TRANSFORMATION TO USEFULLY FUNCTIONALIZED trans-DECALINE DERIVATIVE

Takemoto, Toshiyasu,Nishikimi, Yuji,Sodeoka, Mikiko,Shibasaki, Masakatsu

, p. 3527 - 3530 (2007/10/02)

Treatment of 15 or 16 with Pd(PPh3)4 (10 mol percent) and NaH (1.2 equiv) afforded the cis-decalin derivative 18 stereoselectively in high yield, which was effectively transformed into the usefully functionalized trans-decalin derivative 29.
