Check Digit Verification of cas no

The CAS Registry Mumber 98197-01-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,1,9 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 98197-01:
(7*9)+(6*8)+(5*1)+(4*9)+(3*7)+(2*0)+(1*1)=174
174 % 10 = 4
So 98197-01-4 is a valid CAS Registry Number.

Novel atom-economic reaction: Comprehensive utilization of S-alkylisothiouronium salt in the synthesis of thioethers and guanidinium salts

Gao, Pengchao,Leng, Penglin,Sun, Qi,Wang, Xin,Ge, Zemei,Li, Runtao

, p. 17150 - 17155 (2013)

A novel atom-economic three-component one-pot reaction of a primary amine, an S-alkylisothiouronium salt and a Michael receptor is reported, which affords a guanidinium salt and thioether simultaneously. The guanidine moiety is involved in catalyzing the conjugated Michael addition of the mercaptan. The reaction proceeds under ambient conditions using a non-toxic EtOH-H2O mixture as the solvent, and the two products can be very easily purified. Complete atom economy is achieved by fully utilizing the S-alkylisothiouronium salt and converting the previously wasted mercaptan by-product into the valuable thioether.
