136409-69-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136409-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,4,0 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 136409-69:
(8*1)+(7*3)+(6*6)+(5*4)+(4*0)+(3*9)+(2*6)+(1*9)=133
133 % 10 = 3
So 136409-69-3 is a valid CAS Registry Number.
