136591-52-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136591-52-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,5,9 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 136591-52:
(8*1)+(7*3)+(6*6)+(5*5)+(4*9)+(3*1)+(2*5)+(1*2)=141
141 % 10 = 1
So 136591-52-1 is a valid CAS Registry Number.
