878013-58-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 878013-58-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,8,0,1 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 878013-58:
(8*8)+(7*7)+(6*8)+(5*0)+(4*1)+(3*3)+(2*5)+(1*8)=192
192 % 10 = 2
So 878013-58-2 is a valid CAS Registry Number.
