99986-37-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99986-37-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,8 and 6 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99986-37:
(7*9)+(6*9)+(5*9)+(4*8)+(3*6)+(2*3)+(1*7)=225
225 % 10 = 5
So 99986-37-5 is a valid CAS Registry Number.
