487061-96-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 487061-96-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,8,7,0,6 and 1 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 487061-96:
(8*4)+(7*8)+(6*7)+(5*0)+(4*6)+(3*1)+(2*9)+(1*6)=181
181 % 10 = 1
So 487061-96-1 is a valid CAS Registry Number.
