1355995-71-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1355995-71-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,5,9,9 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1355995-71:
(9*1)+(8*3)+(7*5)+(6*5)+(5*9)+(4*9)+(3*5)+(2*7)+(1*1)=209
209 % 10 = 9
So 1355995-71-9 is a valid CAS Registry Number.
