Check Digit Verification of cas no
The CAS Registry Mumber 2689-70-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,8 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2689-70:
(6*2)+(5*6)+(4*8)+(3*9)+(2*7)+(1*0)=115
115 % 10 = 5
So 2689-70-5 is a valid CAS Registry Number.
