134931-74-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134931-74-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,3 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 134931-74:
(8*1)+(7*3)+(6*4)+(5*9)+(4*3)+(3*1)+(2*7)+(1*4)=131
131 % 10 = 1
So 134931-74-1 is a valid CAS Registry Number.
