134692-28-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134692-28-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,6,9 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134692-28:
(8*1)+(7*3)+(6*4)+(5*6)+(4*9)+(3*2)+(2*2)+(1*8)=137
137 % 10 = 7
So 134692-28-7 is a valid CAS Registry Number.
