134992-93-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134992-93-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,9 and 2 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134992-93:
(8*1)+(7*3)+(6*4)+(5*9)+(4*9)+(3*2)+(2*9)+(1*3)=161
161 % 10 = 1
So 134992-93-1 is a valid CAS Registry Number.
