34992-80-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34992-80-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,9,9 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 34992-80:
(7*3)+(6*4)+(5*9)+(4*9)+(3*2)+(2*8)+(1*0)=148
148 % 10 = 8
So 34992-80-8 is a valid CAS Registry Number.
