Check Digit Verification of cas no
The CAS Registry Mumber 70127-38-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,1,2 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 70127-38:
(7*7)+(6*0)+(5*1)+(4*2)+(3*7)+(2*3)+(1*8)=97
97 % 10 = 7
