936946-39-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 936946-39-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,6,9,4 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 936946-39:
(8*9)+(7*3)+(6*6)+(5*9)+(4*4)+(3*6)+(2*3)+(1*9)=223
223 % 10 = 3
So 936946-39-3 is a valid CAS Registry Number.
