99730-37-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99730-37-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,3 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99730-37:
(7*9)+(6*9)+(5*7)+(4*3)+(3*0)+(2*3)+(1*7)=177
177 % 10 = 7
So 99730-37-7 is a valid CAS Registry Number.
