1283750-37-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1283750-37-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,3,7,5 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1283750-37:
(9*1)+(8*2)+(7*8)+(6*3)+(5*7)+(4*5)+(3*0)+(2*3)+(1*7)=167
167 % 10 = 7
So 1283750-37-7 is a valid CAS Registry Number.

Lian, Zhong,Guan, Xiao-Yang,Shi, Min
, p. 2018 - 2024 (2011/04/17)
In the presence of triphenylphosphine, the reactions of N-protected imines or their precursors with DEAD proceeded smoothly to give the corresponding functionalized 1H-1,2,4-triazole-1,4(5H)-dicarboxylate derivatives in good to high yields under mild cond
