Check Digit Verification of cas no

The CAS Registry Mumber 891087-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,1,0,8 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 891087-91:
(8*8)+(7*9)+(6*1)+(5*0)+(4*8)+(3*7)+(2*9)+(1*1)=205
205 % 10 = 5
So 891087-91-5 is a valid CAS Registry Number.

Synthesis of novel biphenyltetrazole derivatives containing 5-methylisoxazole substituted 1,2,4-triazole

Sun, De-Guang,Hui, Xin-Ping,Xu, Peng-Fei,Zhang, Zi-Yi,Guan, Zuo-Wu

, p. 795 - 801 (2008/02/12)

An efficient route to synthesize the target compounds was developed. Fifteen new 5-[4′-(5-isoxazol-4-aryl-1,2,4-triazol-3-yl-sulfanylmethyl)- biphenyl-2-yl]-tetrazoles derivatives were synthesized. The structures of the new compounds synthesized were confirmed by elemental analyses and spectral data.
