1233239-76-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1233239-76-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,2,3 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1233239-76:
(9*1)+(8*2)+(7*3)+(6*3)+(5*2)+(4*3)+(3*9)+(2*7)+(1*6)=133
133 % 10 = 3
So 1233239-76-3 is a valid CAS Registry Number.
