1234905-82-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1234905-82-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,9,0 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1234905-82:
(9*1)+(8*2)+(7*3)+(6*4)+(5*9)+(4*0)+(3*5)+(2*8)+(1*2)=148
148 % 10 = 8
So 1234905-82-8 is a valid CAS Registry Number.

Yang, Po,Gu, Yi
experimental part, p. 558 - 562 (2011/02/22)
A high-purity benzoxazine (Boz-BOA) containing benzoxazole structure was successfully synthesized by three-step synthetic method using 2-(4-aminophenyl)-1H-benzoxazole-5-amine (BOA) and ortho-hydroxybenzaldehyde. The structure of Boz-BOA was confirmed by
