Check Digit Verification of cas no
The CAS Registry Mumber 135103-70-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,1,0 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 135103-70:
(8*1)+(7*3)+(6*5)+(5*1)+(4*0)+(3*3)+(2*7)+(1*0)=87
87 % 10 = 7
