78160-05-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78160-05-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,1,6 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78160-05:
(7*7)+(6*8)+(5*1)+(4*6)+(3*0)+(2*0)+(1*5)=131
131 % 10 = 1
So 78160-05-1 is a valid CAS Registry Number.
