778647-55-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 778647-55-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,8,6,4 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 778647-55:
(8*7)+(7*7)+(6*8)+(5*6)+(4*4)+(3*7)+(2*5)+(1*5)=235
235 % 10 = 5
So 778647-55-5 is a valid CAS Registry Number.
