Check Digit Verification of cas no
The CAS Registry Mumber 953804-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,3,8,0 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 953804-89:
(8*9)+(7*5)+(6*3)+(5*8)+(4*0)+(3*4)+(2*8)+(1*9)=202
202 % 10 = 2
So 953804-89-2 is a valid CAS Registry Number.
