Check Digit Verification of cas no
The CAS Registry Mumber 866889-02-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,6,8,8 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 866889-02:
(8*8)+(7*6)+(6*6)+(5*8)+(4*8)+(3*9)+(2*0)+(1*2)=243
243 % 10 = 3
So 866889-02-3 is a valid CAS Registry Number.
