223686-64-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 223686-64-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,6,8 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 223686-64:
(8*2)+(7*2)+(6*3)+(5*6)+(4*8)+(3*6)+(2*6)+(1*4)=144
144 % 10 = 4
So 223686-64-4 is a valid CAS Registry Number.
