67935-37-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67935-37-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,9,3 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 67935-37:
(7*6)+(6*7)+(5*9)+(4*3)+(3*5)+(2*3)+(1*7)=169
169 % 10 = 9
So 67935-37-9 is a valid CAS Registry Number.
