87754-12-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87754-12-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,5 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 87754-12:
(7*8)+(6*7)+(5*7)+(4*5)+(3*4)+(2*1)+(1*2)=169
169 % 10 = 9
So 87754-12-9 is a valid CAS Registry Number.
