Check Digit Verification of cas no

The CAS Registry Mumber 1053646-61-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,3,6,4 and 6 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1053646-61:
(9*1)+(8*0)+(7*5)+(6*3)+(5*6)+(4*4)+(3*6)+(2*6)+(1*1)=139
139 % 10 = 9
So 1053646-61-9 is a valid CAS Registry Number.

Practical synthesis of a potent hepatitis C virus RNA replication inhibitor

Bio, Matthew M.,Xu, Feng,Waters, Marjorie,Williams, J. Michael,Savary, Kimberly A.,Cowden, Cameron J.,Yang, Chunhua,Buck, Elizabeth,Song, Zhiguo J.,Tschaen, David M.,Volante,Reamer, Robert A.,Grabowski, Edward J. J.

, p. 6257 - 6266 (2007/10/03)

A practical, efficient synthesis of 1, a hepatitis C virus RNA replication inhibitor, is described. Starting with the inexpensive diacetone glucose, the 12-step synthesis features a novel stereoselective rearrangement to prepare the key crystalline furanose diol intermediate. This is followed by a highly selective glycosidation to couple the C-2 branched furanose epoxide with deazapurine.
