Check Digit Verification of cas no

The CAS Registry Mumber 139926-72-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,2 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139926-72:
(8*1)+(7*3)+(6*9)+(5*9)+(4*2)+(3*6)+(2*7)+(1*2)=170
170 % 10 = 0
So 139926-72-0 is a valid CAS Registry Number.

Stereo- and Regio-controlled Carbon-Carbon Bond Formation Mediated by Tungsten in the s-trans-η4-Diene Cationic Intermediates

Cheng, Ming-Huei,Ho, Yuung-Hsing,Wang, Sue-Lein,Cheng, Chih-Yi,Peng, Shie-Ming,et al.

, p. 45 - 46 (1992)

The tungsten-η3-2-substituted pentadienyl complexes WC5H5(CO)2(syn-η3-2-R-C5H6) (R = COOMe; CMe=CH2) undergo BF3-catalysed stereoselective carbon-carbon bond formation with aldehydes to afford isolable s-trans-diene cations which aft
