Check Digit Verification of cas no
The CAS Registry Mumber 861676-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,1,6,7 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 861676-21:
(8*8)+(7*6)+(6*1)+(5*6)+(4*7)+(3*6)+(2*2)+(1*1)=193
193 % 10 = 3
So 861676-21-3 is a valid CAS Registry Number.
