1335131-21-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1335131-21-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,1,3 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1335131-21:
(9*1)+(8*3)+(7*3)+(6*5)+(5*1)+(4*3)+(3*1)+(2*2)+(1*1)=109
109 % 10 = 9
So 1335131-21-9 is a valid CAS Registry Number.
