Check Digit Verification of cas no
The CAS Registry Mumber 620972-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,0,9,7 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 620972-19:
(8*6)+(7*2)+(6*0)+(5*9)+(4*7)+(3*2)+(2*1)+(1*9)=152
152 % 10 = 2
So 620972-19-2 is a valid CAS Registry Number.
