35443-92-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 35443-92-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,4,4 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 35443-92:
(7*3)+(6*5)+(5*4)+(4*4)+(3*3)+(2*9)+(1*2)=116
116 % 10 = 6
So 35443-92-6 is a valid CAS Registry Number.
