Check Digit Verification of cas no
The CAS Registry Mumber 960009-35-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,6,0,0,0 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 960009-35:
(8*9)+(7*6)+(6*0)+(5*0)+(4*0)+(3*9)+(2*3)+(1*5)=152
152 % 10 = 2
So 960009-35-2 is a valid CAS Registry Number.
