861959-09-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 861959-09-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,1,9,5 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 861959-09:
(8*8)+(7*6)+(6*1)+(5*9)+(4*5)+(3*9)+(2*0)+(1*9)=213
213 % 10 = 3
So 861959-09-3 is a valid CAS Registry Number.
