136573-52-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136573-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,5,7 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 136573-52:
(8*1)+(7*3)+(6*6)+(5*5)+(4*7)+(3*3)+(2*5)+(1*2)=139
139 % 10 = 9
So 136573-52-9 is a valid CAS Registry Number.
