129821-90-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129821-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,8,2 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129821-90:
(8*1)+(7*2)+(6*9)+(5*8)+(4*2)+(3*1)+(2*9)+(1*0)=145
145 % 10 = 5
So 129821-90-5 is a valid CAS Registry Number.
