623931-83-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 623931-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,3,9,3 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 623931-83:
(8*6)+(7*2)+(6*3)+(5*9)+(4*3)+(3*1)+(2*8)+(1*3)=159
159 % 10 = 9
So 623931-83-9 is a valid CAS Registry Number.
