Check Digit Verification of cas no
The CAS Registry Mumber 19647-70-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,6,4 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 19647-70:
(7*1)+(6*9)+(5*6)+(4*4)+(3*7)+(2*7)+(1*0)=142
142 % 10 = 2
So 19647-70-2 is a valid CAS Registry Number.
