135699-49-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135699-49-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,6,9 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 135699-49:
(8*1)+(7*3)+(6*5)+(5*6)+(4*9)+(3*9)+(2*4)+(1*9)=169
169 % 10 = 9
So 135699-49-9 is a valid CAS Registry Number.
