56525-61-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 56525-61-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,5,2 and 5 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 56525-61:
(7*5)+(6*6)+(5*5)+(4*2)+(3*5)+(2*6)+(1*1)=132
132 % 10 = 2
So 56525-61-2 is a valid CAS Registry Number.
