52154-65-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52154-65-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,1,5 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 52154-65:
(7*5)+(6*2)+(5*1)+(4*5)+(3*4)+(2*6)+(1*5)=101
101 % 10 = 1
So 52154-65-1 is a valid CAS Registry Number.
