Check Digit Verification of cas no

The CAS Registry Mumber 1062100-81-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,6,2,1,0 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1062100-81:
(9*1)+(8*0)+(7*6)+(6*2)+(5*1)+(4*0)+(3*0)+(2*8)+(1*1)=85
85 % 10 = 5
So 1062100-81-5 is a valid CAS Registry Number.

A concise and flexible synthesis of the potent anti-influenza agents tamiflu and tamiphosphor

Shie, Jiun-Jie,Fang, Jim-Min,Wong, Chi-Huey

, p. 5788 - 5791 (2008)

(Chemical Equation Presented) Tamiflu and the highly potent neuraminidase inhibitor tamiphosphor have been synthesized in 11 steps and greater than 20% overall yields from an haloarene (1S,2S)-cis-diol. The key transformations include a regio- and stereoselective bromoamidation, and a palladium-catalyzed carbonylation or phosphonylation reaction (see scheme; tamiflu: A = CO 2Et, B = NH3+H2PO4 -, tamiphosphor: A = PO(ONH4)2, B = NH 2).
