Check Digit Verification of cas no

The CAS Registry Mumber 139189-64-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,8 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 139189-64:
(8*1)+(7*3)+(6*9)+(5*1)+(4*8)+(3*9)+(2*6)+(1*4)=163
163 % 10 = 3
So 139189-64-3 is a valid CAS Registry Number.

An advantageous synthesis of 5,6,7,8-tetra-hydrotetrazolo[1,5- a]pyridines

Vonhoff, Stefan,Vasella, Andrea

, p. 551 - 560 (1999)

The one-step synthesis of various O-benzyl-protected glyconotetrazoles from the corresponding glyconolactams is reported. The method is superior to the previously employed cycloaddition of azidonitriles as it uses readily available starting materials and leads to higher yields.
