1332506-42-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1332506-42-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,2,5,0 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1332506-42:
(9*1)+(8*3)+(7*3)+(6*2)+(5*5)+(4*0)+(3*6)+(2*4)+(1*2)=119
119 % 10 = 9
So 1332506-42-9 is a valid CAS Registry Number.
