134332-63-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134332-63-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,3,3 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134332-63:
(8*1)+(7*3)+(6*4)+(5*3)+(4*3)+(3*2)+(2*6)+(1*3)=101
101 % 10 = 1
So 134332-63-1 is a valid CAS Registry Number.
