936619-33-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 936619-33-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,6,6,1 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 936619-33:
(8*9)+(7*3)+(6*6)+(5*6)+(4*1)+(3*9)+(2*3)+(1*3)=199
199 % 10 = 9
So 936619-33-9 is a valid CAS Registry Number.
