136409-57-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136409-57-9 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, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 136409-57:
(8*1)+(7*3)+(6*6)+(5*4)+(4*0)+(3*9)+(2*5)+(1*7)=129
129 % 10 = 9
So 136409-57-9 is a valid CAS Registry Number.
