87745-21-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87745-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,4 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87745-21:
(7*8)+(6*7)+(5*7)+(4*4)+(3*5)+(2*2)+(1*1)=169
169 % 10 = 9
So 87745-21-9 is a valid CAS Registry Number.
