158953-26-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158953-26-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,9,5 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 158953-26:
(8*1)+(7*5)+(6*8)+(5*9)+(4*5)+(3*3)+(2*2)+(1*6)=175
175 % 10 = 5
So 158953-26-5 is a valid CAS Registry Number.
