87605-53-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87605-53-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,0 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 87605-53:
(7*8)+(6*7)+(5*6)+(4*0)+(3*5)+(2*5)+(1*3)=156
156 % 10 = 6
So 87605-53-6 is a valid CAS Registry Number.
