136339-11-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136339-11-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,3,3 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 136339-11:
(8*1)+(7*3)+(6*6)+(5*3)+(4*3)+(3*9)+(2*1)+(1*1)=122
122 % 10 = 2
So 136339-11-2 is a valid CAS Registry Number.
