1335223-99-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1335223-99-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,2,2 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1335223-99:
(9*1)+(8*3)+(7*3)+(6*5)+(5*2)+(4*2)+(3*3)+(2*9)+(1*9)=138
138 % 10 = 8
So 1335223-99-8 is a valid CAS Registry Number.
