87617-77-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87617-77-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,1 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87617-77:
(7*8)+(6*7)+(5*6)+(4*1)+(3*7)+(2*7)+(1*7)=174
174 % 10 = 4
So 87617-77-4 is a valid CAS Registry Number.
