1053642-13-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1053642-13-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,3,6,4 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1053642-13:
(9*1)+(8*0)+(7*5)+(6*3)+(5*6)+(4*4)+(3*2)+(2*1)+(1*3)=119
119 % 10 = 9
So 1053642-13-9 is a valid CAS Registry Number.
