261785-36-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 261785-36-8 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 6 respectively.
Calculate Digit Verification of CAS Registry Number 261785-36:
(8*2)+(7*6)+(6*1)+(5*7)+(4*8)+(3*5)+(2*3)+(1*6)=158
158 % 10 = 8
So 261785-36-8 is a valid CAS Registry Number.
