Check Digit Verification of cas no

The CAS Registry Mumber 83175-77-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,1,7 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 83175-77:
(7*8)+(6*3)+(5*1)+(4*7)+(3*5)+(2*7)+(1*7)=143
143 % 10 = 3
So 83175-77-3 is a valid CAS Registry Number.

PROTECTION OF IMIDE GROUP OF URACIL MOIETY BY MEANS OF 2,2,2-TRICHLORO-TERT-BUTYLOXYCARBONYL CHLORIDE: A SELECTIVE SYNTHESIS OF 2'-O-METHYLURIDINE

Kamimura, Takashi,Masegi, Tsukio,Hata, Tsujiaki

, p. 965 - 968 (2007/10/02)

2,2,2-trichloro-tert-butyloxycarbonyl group (TCBOC) was useful protecting group for the protection of imide function of uracil moiety.Starting from N3-TCBOC uridine derivative, 2'-O-methyluridine was selectively synthesized without formation of N3-methyluridine derivatives.
