135718-34-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135718-34-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,7,1 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 135718-34:
(8*1)+(7*3)+(6*5)+(5*7)+(4*1)+(3*8)+(2*3)+(1*4)=132
132 % 10 = 2
So 135718-34-2 is a valid CAS Registry Number.
