87766-75-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87766-75-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,6 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 87766-75:
(7*8)+(6*7)+(5*7)+(4*6)+(3*6)+(2*7)+(1*5)=194
194 % 10 = 4
So 87766-75-4 is a valid CAS Registry Number.
