886847-85-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 886847-85-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,6,8,4 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 886847-85:
(8*8)+(7*8)+(6*6)+(5*8)+(4*4)+(3*7)+(2*8)+(1*5)=254
254 % 10 = 4
So 886847-85-4 is a valid CAS Registry Number.
