77734-00-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77734-00-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,7,3 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77734-00:
(7*7)+(6*7)+(5*7)+(4*3)+(3*4)+(2*0)+(1*0)=150
150 % 10 = 0
So 77734-00-0 is a valid CAS Registry Number.
