99745-62-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99745-62-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,4 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 99745-62:
(7*9)+(6*9)+(5*7)+(4*4)+(3*5)+(2*6)+(1*2)=197
197 % 10 = 7
So 99745-62-7 is a valid CAS Registry Number.
