Check Digit Verification of cas no
The CAS Registry Mumber 35970-37-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,9,7 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 35970-37:
(7*3)+(6*5)+(5*9)+(4*7)+(3*0)+(2*3)+(1*7)=137
137 % 10 = 7
So 35970-37-7 is a valid CAS Registry Number.
