77425-62-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77425-62-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,2 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77425-62:
(7*7)+(6*7)+(5*4)+(4*2)+(3*5)+(2*6)+(1*2)=148
148 % 10 = 8
So 77425-62-8 is a valid CAS Registry Number.
