135221-26-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135221-26-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,2,2 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 135221-26:
(8*1)+(7*3)+(6*5)+(5*2)+(4*2)+(3*1)+(2*2)+(1*6)=90
90 % 10 = 0
So 135221-26-0 is a valid CAS Registry Number.
