81902-30-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81902-30-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,0 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81902-30:
(7*8)+(6*1)+(5*9)+(4*0)+(3*2)+(2*3)+(1*0)=119
119 % 10 = 9
So 81902-30-9 is a valid CAS Registry Number.
