Check Digit Verification of cas no

The CAS Registry Mumber 1257646-80-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,6,4 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1257646-80:
(9*1)+(8*2)+(7*5)+(6*7)+(5*6)+(4*4)+(3*6)+(2*8)+(1*0)=182
182 % 10 = 2
So 1257646-80-2 is a valid CAS Registry Number.

LNA 5′-phosphoramidites for 5′→3′-oligonucleotide synthesis

Madsen, Andreas Stahl,Kumar, T. Santhosh,Wengel, Jesper

experimental part, p. 5012 - 5016 (2010/11/24)

Hereby we report an efficient synthesis of LNA thymine and LNA 5-methylcytosine 5′-phosphoramidites, allowing incorporation of LNA thymine and LNA 5-methylcytosine into oligonucleotides synthesized in the 5′→3′ direction. Key steps include regioselective
