135958-55-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135958-55-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,9,5 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 135958-55:
(8*1)+(7*3)+(6*5)+(5*9)+(4*5)+(3*8)+(2*5)+(1*5)=163
163 % 10 = 3
So 135958-55-3 is a valid CAS Registry Number.
