Check Digit Verification of cas no
The CAS Registry Mumber 132255-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,2,5 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 132255-83:
(8*1)+(7*3)+(6*2)+(5*2)+(4*5)+(3*5)+(2*8)+(1*3)=105
105 % 10 = 5
So 132255-83-5 is a valid CAS Registry Number.

The invention provides a production method for improving the purity and yield of N,O-bis(trimethyl silyl) acetamide simultaneously. The production method comprises the steps of trimethylchlorosilane preparation, charging, synthetic reaction and distillation. In the step of distillation, front cut fraction is obtained through distillation, and a finished product is obtained through distillation; in the step of trimethylchlorosilane preparation, according to the mole ratio of the trimethylchlorosilane to acetamide being 2.11-2.22:1, the trimethylchlorosilane is sucked into a trimethylchlorosilane overhead tank, and the vacuum degree of the trimethylchlorosilane overhead tank is kept 0.001-0.005 MPa before charging. According to the prepared product BSA, the product purity reaches 99.58-99.66%, the impurity number and content are reduced, and the amine content is 0.20-0.25%; the BSA once through yield reaches 93.42-93.7%, and the raw material conversion rate is high and is improved by more than 3% compared with the prior art.
