35543-23-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 35543-23-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,5,4 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 35543-23:
(7*3)+(6*5)+(5*5)+(4*4)+(3*3)+(2*2)+(1*3)=108
108 % 10 = 8
So 35543-23-8 is a valid CAS Registry Number.
