Check Digit Verification of cas no
The CAS Registry Mumber 64036-72-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,0,3 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 64036-72:
(7*6)+(6*4)+(5*0)+(4*3)+(3*6)+(2*7)+(1*2)=112
112 % 10 = 2
So 64036-72-2 is a valid CAS Registry Number.

Paragraph 0017; 0018, (2018/10/19)
The invention provides 2-amino-4-methylbenzothiazole hydrochloride. A chemical formula is as follow: a formula (I) is shown in the description. A synthesis method of the compound I comprises the following steps: weighing 0.3292g of 2-amino-4-methylbenzothiazole and adding into a 100mL beaker; adding 20mL of anhydrous methanol and continuously stirring; after a solid medicine is dissolved, slowly dropwise adding 1.5mL of concentrated hydrochloric acid; after uniformly stirring, adding 0.2379g of cobalt chloride hexahydrate; after the cobalt chloride hexahydrate is dissolved, slowly adding 10mLof anhydrous ethyl ether (keeping stirring in a whole process); then standing for about 4 days to obtain a colorless and transparent crystal; filtering the crystal and washing with an acidic methanolsolution; drying for 30min in vacuum to obtain a colorless and transparent rhombus-shaped crystal. According to application of the compound I, the compound I has relatively good catalytic performancein Henry reaction of benzaldehyde, and on the benzaldehyde, and the conversion rate reaches 53 percent and 88 percent respectively.
