23185-53-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23185-53-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,1,8 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 23185-53:
(7*2)+(6*3)+(5*1)+(4*8)+(3*5)+(2*5)+(1*3)=97
97 % 10 = 7
So 23185-53-7 is a valid CAS Registry Number.
