Check Digit Verification of cas no
The CAS Registry Mumber 133586-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,8 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133586-89:
(8*1)+(7*3)+(6*3)+(5*5)+(4*8)+(3*6)+(2*8)+(1*9)=147
147 % 10 = 7
So 133586-89-7 is a valid CAS Registry Number.
