Check Digit Verification of cas no

The CAS Registry Mumber 180902-86-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,9,0 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 180902-86:
(8*1)+(7*8)+(6*0)+(5*9)+(4*0)+(3*2)+(2*8)+(1*6)=137
137 % 10 = 7
So 180902-86-7 is a valid CAS Registry Number.

Synthesis of terphenylboronic acid derivatives and recognition of anomers of 2-deoxyribofuranoside

Yamashita, Hiroshi,Amano, Koji,Shimada, Satoru,Narasaka, Koichi

, p. 537 - 538 (1996)

A terphenylboronic acid 1 and its silylated derivative 2 are prepared from (2-nitrophenyl)acetic acid for the purpose of controlling stereochemistry of synthetic organic reactions. These boronic acids are found to recognize α and β-anomers of 2-deoxyribofuranosides. That is, when these boron compounds are added to a 1 : 1 mixture of α and β-t-butyl 5-O-benzyl-2-deoxy-D-ribofuranosides, the boronic acids 1 and 2 form the corresponding boronates preferentially with the β-anomer.
