Check Digit Verification of cas no

The CAS Registry Mumber 1222981-70-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,2,9,8 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1222981-70:
(9*1)+(8*2)+(7*2)+(6*2)+(5*9)+(4*8)+(3*1)+(2*7)+(1*0)=145
145 % 10 = 5
So 1222981-70-5 is a valid CAS Registry Number.

Figure presented The first asymmetric total synthesis of fluvirucinine A2 has been accomplished. A key feature of the synthesis is an iterative lactam ring expansion to provide rapid access to the 14-membered lactam skeleton and three stereogenic centers. The excellent remote control of the three stereogenic centers relied on stereoselective amidoalkylation followed by an amide-enolate-induced aza-Claisen rearrangement. In addition, the structure of fluvirucinine A2 has been completely elucidated by our total synthesis.
