83753-81-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83753-81-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,7,5 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 83753-81:
(7*8)+(6*3)+(5*7)+(4*5)+(3*3)+(2*8)+(1*1)=155
155 % 10 = 5
So 83753-81-5 is a valid CAS Registry Number.
