135241-01-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135241-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,2,4 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 135241-01:
(8*1)+(7*3)+(6*5)+(5*2)+(4*4)+(3*1)+(2*0)+(1*1)=89
89 % 10 = 9
So 135241-01-9 is a valid CAS Registry Number.
