99902-38-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99902-38-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,0 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99902-38:
(7*9)+(6*9)+(5*9)+(4*0)+(3*2)+(2*3)+(1*8)=182
182 % 10 = 2
So 99902-38-2 is a valid CAS Registry Number.
