78115-65-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78115-65-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,1,1 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78115-65:
(7*7)+(6*8)+(5*1)+(4*1)+(3*5)+(2*6)+(1*5)=138
138 % 10 = 8
So 78115-65-8 is a valid CAS Registry Number.
