83548-75-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83548-75-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,4 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 83548-75:
(7*8)+(6*3)+(5*5)+(4*4)+(3*8)+(2*7)+(1*5)=158
158 % 10 = 8
So 83548-75-8 is a valid CAS Registry Number.
