261785-33-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 261785-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,1,7,8 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 261785-33:
(8*2)+(7*6)+(6*1)+(5*7)+(4*8)+(3*5)+(2*3)+(1*3)=155
155 % 10 = 5
So 261785-33-5 is a valid CAS Registry Number.
