631090-69-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 631090-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,1,0,9 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 631090-69:
(8*6)+(7*3)+(6*1)+(5*0)+(4*9)+(3*0)+(2*6)+(1*9)=132
132 % 10 = 2
So 631090-69-2 is a valid CAS Registry Number.
