171877-93-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 171877-93-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,8,7 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 171877-93:
(8*1)+(7*7)+(6*1)+(5*8)+(4*7)+(3*7)+(2*9)+(1*3)=173
173 % 10 = 3
So 171877-93-3 is a valid CAS Registry Number.

, p. 2739 - 2747 (2007/10/03)
2,5:3,4-Dianhydro-L-talofuranose dimethylacetal 7 was synthesized from D-glucose in 7 steps. A series of 4-deoxy-4-nucleobase-2,5-anhydro-L-mannitols 13-16 were synthesized regioselectively from 7 in good yields. 6-O-p-Tolylsulfonyl-2,5:3,4-dianhydro-L-ta
