Check Digit Verification of cas no

The CAS Registry Mumber 1257334-80-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,3,3 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1257334-80:
(9*1)+(8*2)+(7*5)+(6*7)+(5*3)+(4*3)+(3*4)+(2*8)+(1*0)=157
157 % 10 = 7
So 1257334-80-7 is a valid CAS Registry Number.

A new method for the synthesis of iminoquinones via DMP-mediated oxidative reaction

Ma, Hengchang,Wu, Shang,Sun, Qiangsheng,Li, Hongyan,Chen, Yannan,Zhao, Wenqing,Ma, Bihui,Guo, Qing,Lei, Ziqiang,Yan, Jun

experimental part, p. 3295 - 3300 (2010/11/20)

Iminoquinones were synthesized by oxidation of primary and secondary amines with hypervalent iodine reagent Dess-Martin periodinane in average to good yields, and possible mechanisms were postulated. This methodology is convenient to establish a library of diversified iminoquinone compounds and has great significance for their potential application in the field of pharmaceuticals.
