35402-57-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 35402-57-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,4,0 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 35402-57:
(7*3)+(6*5)+(5*4)+(4*0)+(3*2)+(2*5)+(1*7)=94
94 % 10 = 4
So 35402-57-4 is a valid CAS Registry Number.
