Check Digit Verification of cas no
The CAS Registry Mumber 303766-96-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,7,6 and 6 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 303766-96:
(8*3)+(7*0)+(6*3)+(5*7)+(4*6)+(3*6)+(2*9)+(1*6)=143
143 % 10 = 3
So 303766-96-3 is a valid CAS Registry Number.
