Check Digit Verification of cas no
The CAS Registry Mumber 1089687-02-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,9,6,8 and 7 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1089687-02:
(9*1)+(8*0)+(7*8)+(6*9)+(5*6)+(4*8)+(3*7)+(2*0)+(1*2)=204
204 % 10 = 4
So 1089687-02-4 is a valid CAS Registry Number.
