Check Digit Verification of cas no
The CAS Registry Mumber 212779-19-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,7,7 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 212779-19:
(8*2)+(7*1)+(6*2)+(5*7)+(4*7)+(3*9)+(2*1)+(1*9)=136
136 % 10 = 6
So 212779-19-6 is a valid CAS Registry Number.
