Check Digit Verification of cas no

The CAS Registry Mumber 103209-78-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,2,0 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 103209-78:
(8*1)+(7*0)+(6*3)+(5*2)+(4*0)+(3*9)+(2*7)+(1*8)=85
85 % 10 = 5
So 103209-78-5 is a valid CAS Registry Number.

Peptide Synthesis in Aqueous Solution. V. Properties and Reactivities of (p-Hydroxyphenyl)benzylmethylsulfonium Salts for Direct Benzyl Esterification of N-Acylpeptides

Nakata, Takashi,Nakatani, Masaru,Takahashi, Masatoshi,Okai, Jiro,Kawaoka, Yoshiaki,Kouge, Katsushige,Okai, Hideo

, p. 1099 - 1106 (2007/10/03)

Some (p-hydroxyphenyl)benzylmethylsulfonium salts were prepared. These compounds generated a benzyl cation and converted not only N-acylamino acids but also N-acylpeptides into their corresponding benzyl esters without causing the racemization.
