Check Digit Verification of cas no

The CAS Registry Mumber 33328-21-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,3,2 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 33328-21:
(7*3)+(6*3)+(5*3)+(4*2)+(3*8)+(2*2)+(1*1)=91
91 % 10 = 1
So 33328-21-1 is a valid CAS Registry Number.

Facile synthesis of S-arylisothioureas via the S-arylation of arylthioureas with aryl iodides in water

Liu, Xing,Zhu, Hui,Zhang, Shi-Bo,Cheng, Yu,Peng, Han-Ying,Dong, Zhi-Bing

, p. 3165 - 3170 (2018)

An environmentally benign, simple and highly efficient protocol for the synthesis of S-arylisothiourea derivatives has been achieved in good to excellent yields by reacting a series of aryl iodides with arylthioureas, using inexpensive CuSO4·5H2O as catalyst in water without PTC (phase transfer catalyst). The protocol features easy performance, good to excellent yields, good tolerance towards a variety of functional groups, which could be useful for the preparation of some biologically active compounds.
