Check Digit Verification of cas no

The CAS Registry Mumber 94189-94-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,1,8 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 94189-94:
(7*9)+(6*4)+(5*1)+(4*8)+(3*9)+(2*9)+(1*4)=173
173 % 10 = 3
So 94189-94-3 is a valid CAS Registry Number.

A CONVENIENT METHOD FOR THE FORMATION OF INTERNUCLEOTIDE LINKAGE

Hayakawa, Y.,Uchiyama, M.,Noyori, R.

, p. 4003 - 4006 (2007/10/02)

Internucleotide linkage can be made readily by reaction of N-unprotected nucleosides and phosphorochloridates or p-nitrophenyl phosphates by the assistance of Grignard reagents.
