Check Digit Verification of cas no

The CAS Registry Mumber 186972-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,9,7 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 186972-20:
(8*1)+(7*8)+(6*6)+(5*9)+(4*7)+(3*2)+(2*2)+(1*0)=183
183 % 10 = 3
So 186972-20-3 is a valid CAS Registry Number.

Synthesis of an antifreeze glycoprotein analogue: Efficient preparation of sequential glycopeptide polymers

Tsuda, Tetsuro,Nishimura, Shin-Ichiro

, p. 2779 - 2780 (2007/10/03)

A sequential glycopeptide polymer, antifreeze glycoprotein (AFGP) 1, was efficiently synthesised by simple polymerisation of the repeating glycopeptide unit of AFGP 10 with diphenylphosphoryl azide (DPPA) as a convenient promotor.
