135446-01-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135446-01-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,4,4 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 135446-01:
(8*1)+(7*3)+(6*5)+(5*4)+(4*4)+(3*6)+(2*0)+(1*1)=114
114 % 10 = 4
So 135446-01-4 is a valid CAS Registry Number.
