691860-36-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 691860-36-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,1,8,6 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 691860-36:
(8*6)+(7*9)+(6*1)+(5*8)+(4*6)+(3*0)+(2*3)+(1*6)=193
193 % 10 = 3
So 691860-36-3 is a valid CAS Registry Number.
