23571-42-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23571-42-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,5,7 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 23571-42:
(7*2)+(6*3)+(5*5)+(4*7)+(3*1)+(2*4)+(1*2)=98
98 % 10 = 8
So 23571-42-8 is a valid CAS Registry Number.
