Check Digit Verification of cas no

The CAS Registry Mumber 1228425-04-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,4,2 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1228425-04:
(9*1)+(8*2)+(7*2)+(6*8)+(5*4)+(4*2)+(3*5)+(2*0)+(1*4)=134
134 % 10 = 4
So 1228425-04-4 is a valid CAS Registry Number.

Anodic oxidation of catechols in the presence of α-oxoketene N,N-acetals with a tetrahydropyrimidine ring: Selective α-arylation reaction

Zeng, Cheng-Chu,Ping, Da-Wei,Hu, Li-Ming,Song, Xiu-Qing,Zhong, Ru-Gang

experimental part, p. 2465 - 2472 (2010/07/06)

The electrochemical oxidation of catechols leads to the formation of o-benzoquinones. This property has been applied to effectively synthesize α-arylated products of α-oxoketene N,N-acetals with a tetrahydropyrimidine ring.
