77151-48-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77151-48-5 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 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77151-48:
(7*7)+(6*7)+(5*1)+(4*5)+(3*1)+(2*4)+(1*8)=135
135 % 10 = 5
So 77151-48-5 is a valid CAS Registry Number.
