Check Digit Verification of cas no
The CAS Registry Mumber 433701-09-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,3,7,0 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 433701-09:
(8*4)+(7*3)+(6*3)+(5*7)+(4*0)+(3*1)+(2*0)+(1*9)=118
118 % 10 = 8
So 433701-09-8 is a valid CAS Registry Number.
