Check Digit Verification of cas no
The CAS Registry Mumber 1136478-29-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,6,4,7 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1136478-29:
(9*1)+(8*1)+(7*3)+(6*6)+(5*4)+(4*7)+(3*8)+(2*2)+(1*9)=159
159 % 10 = 9
So 1136478-29-9 is a valid CAS Registry Number.
