77152-25-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77152-25-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,5 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77152-25:
(7*7)+(6*7)+(5*1)+(4*5)+(3*2)+(2*2)+(1*5)=131
131 % 10 = 1
So 77152-25-1 is a valid CAS Registry Number.
