Check Digit Verification of cas no
The CAS Registry Mumber 690678-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,0,6,7 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 690678-19:
(8*6)+(7*9)+(6*0)+(5*6)+(4*7)+(3*8)+(2*1)+(1*9)=204
204 % 10 = 4
So 690678-19-4 is a valid CAS Registry Number.
