Check Digit Verification of cas no
The CAS Registry Mumber 1019638-19-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,9,6,3 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1019638-19:
(9*1)+(8*0)+(7*1)+(6*9)+(5*6)+(4*3)+(3*8)+(2*1)+(1*9)=147
147 % 10 = 7
So 1019638-19-7 is a valid CAS Registry Number.
