Check Digit Verification of cas no
The CAS Registry Mumber 867313-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,7,3,1 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 867313-40:
(8*8)+(7*6)+(6*7)+(5*3)+(4*1)+(3*3)+(2*4)+(1*0)=184
184 % 10 = 4
So 867313-40-4 is a valid CAS Registry Number.
