136539-99-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136539-99-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,5,3 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 136539-99:
(8*1)+(7*3)+(6*6)+(5*5)+(4*3)+(3*9)+(2*9)+(1*9)=156
156 % 10 = 6
So 136539-99-6 is a valid CAS Registry Number.
