135128-01-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135128-01-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,1,2 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 135128-01:
(8*1)+(7*3)+(6*5)+(5*1)+(4*2)+(3*8)+(2*0)+(1*1)=97
97 % 10 = 7
So 135128-01-7 is a valid CAS Registry Number.
