1151528-25-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1151528-25-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,1,5,2 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1151528-25:
(9*1)+(8*1)+(7*5)+(6*1)+(5*5)+(4*2)+(3*8)+(2*2)+(1*5)=124
124 % 10 = 4
So 1151528-25-4 is a valid CAS Registry Number.
